People think that geography is about capitals, landforms and so on. But it is also about place — its emotional tone, social meaning, and generative potential.”

—Yi-Fu Tuan

Tuan was a prolific writer and deep thinker who was known as the father of humanistic geography. A movement within the field of human geography, humanistic geography arose in the 1970s as a way to counter what humanists saw as a tendency to treat places as mere sites or locations. Instead, a humanistic geographer would argue, the places we inhabit have as many personalities as those whose lives have intersected with them. And the stories we tell about places often say as much about who we are, as about where our feet are planted.

It was Tuan who gave rise to the recognition among geographers that the intimacies of personal encounters with space produce a “sense of place.”

“People think that geography is about capitals, landforms and so on,” Tuan said. “But it is also about place — its emotional tone, social meaning, and generative potential.”

Time, age, sadness, loss, goodness, happiness, and the concept of home are all themes Tuan explored at length in his more than 20 books, including his best-known work, “Space & Place,” as well as “Humanist Geography: An Individual’s Search for Meaning.” In his later years, Tuan turned to introspection with his most recent books: “Who Am I?  An Autobiography of Emotion, Mind and Spirit” and an addendum, “Who Am I? A Sequel.” Both works look back on the author’s early life in China and his rise to become one of America’s most innovative intellectuals.

Born in 1930 in Tianjin, China, Yi-Fu Tuan was educated in China, Australia, the Philippines and the United Kingdom. He received his bachelor’s and master’s degrees from the University of Oxford and his doctorate from the University of California, Berkeley.

Yi-Fu Tuan joined the faculty of the Department of Geography at UW–Madison in 1983, was named John Kirtland Wright Professor of Geography in 1985 and was named a Vilas Research Professor that same year, before attaining emeritus status in 1998.

His influence on the field of geography was enormous.

“For decades, Yi-Fu Tuan’s work shaped the thinking of generations of geography students and academics,” says Lily Kong, human geographer and president, Singapore Management University. “His place in the geographical canon is undoubted. His shaping of humanistic geography contributed to important philosophical shifts in the discipline.”

By emphasizing humans as thinking, dreaming, imagining beings who experience the world — capable of goodness, beauty and truth as well as greed, cruelty and domination — he showed us how all of these traits are reflected in our spaces, places and landscapes.”

—Tim Cresswell

Tuan was beloved by his students, both graduate and undergraduate alike. He often shared meals with undergraduates and enjoyed visiting the State Street Starbucks to listen in on, and sometimes join, students’ conversations about their studies.

“Yi-Fu Tuan insisted on the importance of the “human” in “human geography,” says Tim Cresswell, a graduate student of Tuan’s at UW–Madison who is now Ogilvie Professor of Geography at the University of Edinburgh. “By emphasizing humans as thinking, dreaming, imagining beings who experience the world — capable of goodness, beauty and truth as well as greed, cruelty and domination — he showed us how all of these traits are reflected in our spaces, places and landscapes.”

Tuan opened geography to scholars in other disciplines, according to Cresswell, and invited thinking on what geography had to offer our understanding of the human condition. Tuan’s work was cited and celebrated by scholars across the arts, humanities and social sciences, as well as by writers and professionals outside academia.

After his retirement, Tuan remained an emphatic presence on campus. Through his books, essays, and letters, as well as through innumerable conversations with students, Tuan continued to profoundly influence scholarship and thinking. An article about Yi-Fu Tuan in The Chronicle of Higher Education, 13 years after his retirement from UW–Madison, claimed that the geographer “may be the most influential scholar you’ve never heard of.” His world-renowned stature was complemented by a kind and generous demeanor, an intense curiosity about the world, and a keen interest in how his beloved department was evolving over the years. He was a model university scholar and citizen, says Kris Olds, a professor in the Department of Geography.

In Oct. 2012, Tuan was awarded the Vautrin-Lud International Geography Prize, the highest honor a geographer can receive. In 2013, he received the inaugural American Association of Geographers Stanley Brunn Award for Creativity in Geography, created to recognize “originality, creativity, and significant intellectual breakthroughs in geography.”

One of Tuan’s most unique contributions may be his “Dear Colleague” letters, composed over decades and sent to colleagues and friends, relating observations and changes in his daily life against a backdrop of larger political, educational, and social change.

“I do not know what Yi-Fu would like to say to everyone at the department in his last ‘Dear Colleague’ letter on Earth,” says Charles Chang. “But I do know that in his first ‘Dear Colleague’ letter from (hopefully) Heaven, he would like to thank them for their support over all these years.”

Chang also pointed to a story Tuan shared in an unpublished manuscript entitled “Summing Up,” in 2019.

“One day, as I walked down State Street, I heard the voice of a child behind me saying repeatedly, ‘Are you a student?’ Tuan wrote. “I ignored the question, for it could hardly be addressed to me. But I got curious, turned around, and asked the child, ‘Now, look here, do I look like a student?’ His reply, ‘Yes, you have a backpack.’ Well, that made my day! I have a backpack, which means that I am a student still open to life.”

“In a broad sense,” Chang says, “he was always open to life. He remained an active learner of the cosmos, of human goodness, to the end.”

Education: MS in Geographic Information Science (San Diego State University), BS in Architecture (University of Colorado Denver)

The following profile was compiled by Jessica Embury (San Diego State University) for the Encoding Geography initiative. To learn more, visit: https://www.ncrge.org/encoding-geography/


Please describe your job, employer, and the primary tasks that you perform in your position. 

I am currently a GIS web developer for a mid-sized engineering firm of about 600 people that has offices in Minnesota, Texas, and Colorado. My primary tasks are geospatial scripting for various locations and tracking different types of assets, like cranes and street sweepers. I also work on web mapping applications that are generally used by cities and counties to manage tax data, parcel data, or stormwater information. I work on other applications for the oil and gas industry, like helping manage location audits and tracking different types of surveys on job sites throughout Texas.   

Previously, I’ve worked on EPA projects, like a common operating picture, which was essentially an emergency response platform. It had various assets and information brought into it regarding wildfires and other things. I’ve also worked on geospatial scripting for generating time enabled smoke imagery mosaics where I took cams and files from the Forest Service’s Blue Sky platform and translated that into a time enabled hosted and managed service. 

Other projects I’ve worked on were Native American tribal nations software, like central data management systems for managing water quality, collecting surveys from research scientists, and managing environmental cleanup. 

What is your educational background? How did you initially discover geocomputation and why did you ultimately choose a career that uses geography and computer science? 

My bachelor’s degree is in architecture and that’s where I was first introduced to GIS, in a natural hazards course. It’s how I got interested in wildfires and learning about GIS and what I could do with it. I also took an architectural cartography course which covered using GIS data to visualize changes in Denver, where I went to school.  

After working in architecture for a couple years, I just didn’t enjoy it and I always loved geography so I was hoping I could use some of my experience regarding planning, knowledge of fire, and building codes and somehow apply GIS to work with wildfires. Then, I completed my masters at San Diego State University and did my thesis on geovisualization and descriptive analysis of landscape level wildfire behavior using repeat pass airborne thermal imagery.  

During that time, I developed web applications for visualizing different attributes of landscapes and wildfire behaviors, such as reduced spread. I also did a descriptive analysis and worked on a couple other projects using GIS. 

I ultimately chose a career in geocomputation because I really liked the programming side of it. I thought it was an interesting and powerful skill set for being able to work with GIS data that not a lot of people have. I felt it also helped to have programming skills when I graduated and got into the job market. 

Is GIS usage widespread in architecture education and the industry? 

No, it is primarily used by planners but not really in architecture. If you work with site plans for master planning communities then you might get a little more experience. I worked in multifamily architecture so I got some experience using GIS to edit line work for a community master plan in Colorado, but that was the extent of it. Most architects I’ve met never use GIS. They do a lot of 3D modeling and data information modeling, but that’s about it.  

When you think about geography, what specific background knowledge and conceptual ideas are important and useful to know? 

Something that I feel is really under-represented in geographic education is learning how to work with coordinate systems and geographic versus projected coordinate systems. I run into a lot of issues in my job where people aren’t familiar with those concepts and then they don’t understand why certain tools aren’t working or what data processes are happening.  

Working with different data types and understanding how a database is structured is really helpful, but that’s more specific to a development role. Also, being familiar with common tools and processes for editing vector data and evaluating the accuracy of GPS data. I think having familiarity with GIS and data standards are the most important for a geospatial developer.  

When thinking about computer science, what specific background knowledge and conceptual ideas do you think are important and useful to know? 

For a web GIS developer, understanding how websites work is important,  like what happens when you type in a URL and how data is tasked between different services. For example, if you have a GIS server instance, how do you get data from that? A broad level of knowing how a REST API works is really important and critical for using geospatial data in websites. Also, having a general understanding of relational databases and becoming comfortable with certain programming languages are big skills.  

What procedural knowledge do you think is important and useful to know, from either geography or computer science? 

From geography, or the computer science side of geography, I think it’s really important to be familiar with Esri products like ArcGIS Pro or ArcDesktop, because those are widely used, especially in cities and municipalities. Then, understanding what Esri portal and enterprise are and how to use ArcGIS Online. Even as a developer, I use those tools all the time.  

Getting a little more into the computer science part, it is important to know how to use ArcPy and the ArcGIS Python API, as well as open source software. I haven’t used QGIS recently but I think that’s a good one to learn if you don’t have access to other GIS. Then, being familiar with libraries such as GDAL and OGR for Python is really helpful. Also, knowing how to set up a PostGIS database is a specific skill that’s really helpful for the computer science part. I mainly work with Javascript, Typescript, Python, a little bit of C# (C-Sharp).  

With web development, I also use HTML and CSS. If you’re going to be a web developer, you need to know the basics of vanilla JavaScript, which is what they call using JavaScript without a framework. Understanding how to make a call to a REST endpoint and how to get data from a host or feature service is really important. Generally understanding the life cycle, like a promise in JavaScript is important, so if you get data you’re leaving that response. Then understanding the DOM, the document object model, and how that works. Essentially, how is an html page structured and then, depending on what resources you use, knowing a rest API and how that works. You could also look into a soap API which uses xml. I did run into that a little bit, especially larger scale stuff. We essentially had a big repository for data that was used by Federal Government employees and now it’s translated from xml. So that’s the specific programs stuff.  

Then, for Python, you should know some of the big geospatial libraries and know when it’s appropriate to use certain things and that just takes time. Then, if you want to get a job, it’s helpful to know a framework and have something that you’ve built, have examples of work that you’ve done, no matter how small they are, but have examples of a small portfolio and if you can explain what’s happening behind the scenes – then that’s pretty critical to getting a job in the field. 

What is an example of a social, economic, environmental or other issue that you recently investigated in a project at work? 

We work mostly with environmental issues. I’m currently working on a stormwater asset management program so it uses some hydrological modeling that’s above my head, but essentially it’s a program which can forecast when stormwater basins and ponds will need maintenance, so preserving stormwater ponds in different communities throughout Minnesota.  

Another project I worked on is the EPA common operating picture, and for that I worked on a few different widgets and a web map and one of them, for environmental data, was that smoke mosaic data. We set up a script to run every 24 hours and update daily [to] provide information on particle density for smoke over California, Nevada, and a couple other states in the southwest US. Another component of that was tracking active fire perimeters and if there were active fire parameters within 10 miles of an EPA facility, [then] that would notify people. 

What kind of geographic or computational questions did you ask and think about during your project? 

I’ll talk about the smoke data because that’s really interconnected with air quality, which can be interconnected to a lot of other social and environmental issues related to people who are disproportionately affected by that. The question is, from a technical standpoint, how do we transform these cams and the files into something that’s useful and time-enabled? Then, how do we convey that knowledge to somebody who doesn’t have a GIS background? And how can we make it useful at the scale? So the scale of this data is multiple states, the lower 48 states of the contiguous U.S..  

Knowing how to resample that imagery was important, so how do we make sure that it’s an appropriate scale and spatial resolution for the task at hand? Then, that kind of blended into programming, so this would be kind of a classic geospatial scripting – You’re transforming the data, so you first need to get the data, so you make a request to that site and get the data, unzip it, then you need to organize it. For that dataset we had times in each image file name, so you could just use Python to pull out the dates, and then you need to transform it into the correct projection. You need to reproject those rasters and then, once you do that, you can look at the different types of resampling that you can do. Then, once you have all your data finished and you finished the processing of your data, you then need to work on the final product. So you kind of have these iterative steps to clean the data, get it in a format you want, and make sure it’s displaying correctly at an appropriate spatial resolution or appropriate coordinate system. 

And then, once that’s done, you can do the final task, which is essentially creating an image service that you can just put in a web app that has time enabled on it, which is an Esri specific thing, because if you enable time on this image layer, then you can use all these different filtering tools to visualize the data. 

What types of data did you acquire to support your project? If possible, please identify up to three data sets you utilize the most. 

So we used the BlueSky daily runs from the WebSky platform from the United States Forest Service, which is a research model that they generate for different regions in the U.S.. 

https://tools.airfire.org/websky/v2/#status  

For the EPA, we used a couple different datasets. I don’t know how much I can talk about that, but we did use the classic U.S. main fire perimeter data: the NIFC current wildfire perimeters data set. Currently, we use a lot of parcel tax data, so that’s more specific to city and county level, but I would say we work with that the most. 

What type of content knowledge and skills did you use to evaluate, process, and analyze the data that you gathered for your project? 

For the remote sensing part of that project, it was about understanding the different types of interpolation, such as nearest neighbor, and resampling methods for raster data. Also, being able to identify your destination coordinate system and apply any projections that you need.  

Content knowledge and skills specifically for programming would be understanding how to use Open Source  geoproducts, so in that case it was GDAL to work with raster data. Then principles for more general types of skills like Python programming and using Jupyter notebooks or ArcGIS notebooks to schedule a task to run every 24 hours to get new data and republish the image service. 

As a developer, I get a lot of hard skills but the soft skills can be ignored a little bit. The most important thing I’ve learned is being able to explain to somebody why something is important if they don’t have a background in GIS and being able to distill the work you’re doing and provide a high level summary. That’s something we have to do all the time. An example of this would be when I built a continuous integration continuous development pipeline for a client. What this does is it builds their application tests and it deploys it to wherever they want automatically. So I had to be able to distill this really technical process of backing up and restoring databases and running certain types of integration tests to a client that doesn’t really have a strong computer science background and I’m just a GIS technician. That was for a Tribal Nations organization. So how you distill that knowledge upwards and explain what you’re doing and why it’s meaningful is the most important part of this process. 

How did you apply geography and computer science to communicate the results of your project? Do you have a recent product or publication that you can share as an example? 

I primarily use web applications. I don’t usually use maps very often, unless they’re embedded in a web application. So I do a lot of mapping applications where geovisualization is an important part of that.   

How to display data in a meaningful way is always important, even at city levels, if they have huge data sets, like a lot of utility data sets and storm water and sewer and parcel. A lot of them have tons of data, so how do you display that data in a way that doesn’t get super cluttered or confusing? 

For a recent product, we have a public facing web page. This is another product for oil and gas. There is a video on this website that does a little walkthrough: 

https://www.wsbeng.com/expertise/technology/solutions/datafi/ 

WSB Engineering and Innovate! Inc. are the two companies I’ve worked for. I wanted to work in-person. I think it is important to have that in-person mentorship as a developer. 

Reflecting on your work, how does it align with your personal values and your community or civic interests? 

I’ve been able to explore some environmental issues that generally align well with my personal values. I feel like I get to make a positive impact, and even with fields and sectors of oil and gas that I wouldn’t necessarily see myself working in, I like that I get to help with environmental compliance and making sure that field workers are safe and sticking to appropriate procedures.  

I really enjoyed the work I did for the Environmental Protection Agency. That’s probably been the highlight so far – being able to work for an agency that I admire. Being able to work with the Forest Service is great too. Most of my work is related to environmental issues, which I’m passionate about, but it would also be great to use this data for other civic or social justice projects to see how GIS data can be useful for that.

Tom Paper

Education: B.A. in Economics (Williams College), M.B.A. in General Management (Stanford University)

The following includes an interview conducted with two colleagues at Webster Pacific. Although the conversation with both Tom Paper and William Blomstedt is included below, a duplicate profile is also available for William Blomstedt, who is GIS Expert and Project Manager at Webster Pacific.

It was compiled by Jessica Embury (San Diego State University) for the Encoding Geography initiative. To learn more, visit: https://www.ncrge.org/encoding-geography/


Please describe your job, employer, and the primary tasks that you perform in your position. 

Tom Paper (TP): Our company is Webster Pacific and we provide analytical consulting services. We’ve been in business for almost 20 years and our clients are in a wide range of industries. I used to be a strategy consultant at Bain and Company a long time ago.   

We use tools like Python, ArcGIS, Tableau/PowerBI, CRM/ERP, Cloud Databases, and SQL Server to perform coding, geo-analysis, marketing analytics, web scraping/research, interviewing, and financial analysis. I can’t use any of these programs but I understand the logic of all the work that we do, much of which is geocomputational. 

William, do you want to add anything? You have a background in geoscience. 

William Blomstedt (WB): I studied geography as an undergrad and then I did a master’s course in GIS so I came to the field that way. Tom, geospatially, you only started more recently doing geospatial stuff? The work evolved to geospatial analysis. 

TP: That’s right, seven years ago, one of our clients – a private school based in Manhattan – wanted to open up schools in cities all over the world and asked us to help them analyze cities as opportunities for locating new schools. And that’s what launched us. We evolved our geospatial capabilities for this particular client to help other clients and other schools think geospatially about new locations. We just helped a preschool in Washington DC and we also helped a private school think about why a location in San Francisco had not been performing as well. 

What is your educational background and how did you initially discover geocomputation and ultimately choose a career using geography and computer science? 

TP: My background was liberal arts. I studied economics and environmental studies at Williams and so I don’t know whether the career chose me or if I chose the career. It feels a little bit like it chose me. I think for William – he chose it, he was more curious geospatially early on.  

In the last five years, pretty much since we started geospatial analytics, I got interested in antique maps and that process of discovery. I think there’s a very real thread between our work and the kind of work that people did to think about exploration. For example, I have a map of California as an island from the 17th century. I think it was George Box who said, “All models are wrong, but some are useful.” Examples of things being wrong fascinate me because we see that every day, or we know our models are wrong, but the question is whether they are helpful. 

When thinking about geography, what specific background knowledge and conceptual ideas do you think are important and useful? 

TP: I think that the ability to think in the weeds and then to think about the forest is the most important skill that we have. To be able to go back and forth between details and the big picture. I don’t have a geographic education but I think that ability is critical to what we do every day.  

WB: When I was choosing to go to school to pursue geography, someone told me that you could take a GIS course that just teaches you how to use the program and do GIS. However, they advised me to go to a course where you do a thesis where you have to solve a problem, and GIS is the tool. Instead of just learning the tool, you need to use the tool to do something with it and think about the big picture, rather than just doing geographical analysis. 

When thinking about computer science, what specific background knowledge and conceptual ideas do you think are important and useful? 

TP: I think the willingness to accept that you don’t know everything and that there are things that we still learn. Repeatedly, we learn things and how to do things that we didn’t know before, so I think the willingness to accept that you don’t know everything is critically important.  

Can you mention any procedural knowledge that you think is particularly useful from the standpoint of either geography or computer science? 

TP: We see geography and computer science, or geospatial, like they’re melded together: geography and computer science and our use of programs.  

We use Excel and Google Sheets all the time because it’s how we get into the details and also get to the big picture. Now we’ve had a lot of young people join our firm and want to use Python instead of Excel. I’m not sure I would say that I have embraced it, but I can see the power of it. No matter how programmatic they get, it is important that our team understands how to come back to the larger questions and more conceptual ways of displaying what we’re doing.  

We’re fortunate in the sense that we are driven by our client and their strategy. Every client has a different definition of what is a customer to them and their market position. The priorities are the activities that support that market position and determine who is a customer, and how to spatially define a customer in a particular space. We often think about time. We do find that mileage is not good because a mile in New York City and a mile in Los Angeles are very different due to the time it takes people to get to and from things.  

What’s an example of a social, economic, environmental or other issue that you recently investigated in a project? 

TP: Our client wanted to find a location within a metropolitan area and the customers who would go to their store. Customers are only willing to travel so far. So we wanted to locate in a place where there’s more demand than competing supply for this company. We created a map to show demand and supply in the market. The basic point was to figure out where there’s more demand than supply. Geospatially, where does that exist? We took the demand and subtracted out the supply to get our answer. If all you were doing was looking at the demand, you’d get an answer that looks very different.  

What kind of questions did you ask and think about during this project? 

WB: It’s all about location, place, and interconnection. If we need to write a code or an algorithm, we do it to either iterate faster or to make a model. For a simple supply model, we can say the supply is all in one point. In a more complex model, we will say the supply is not exactly in that point but it’s around that point (e.g. within 10 minutes) and so we have to build a model which spreads that supply out and then computationally figure out where all the supply is.  

What types of data did you acquire to support your project, and are you able to identify up to three data sets that you use frequently? 

TP: We use Census data a lot.  

WB: American Community Survey. 

TP: We use lists of schools or stores on the web. Our client will also have data about their customers and information that we will integrate into our analysis.   

But Census data is by far the biggest one. For the census data, we deal with shapefiles. Sometimes we get data by Block Group, Census Tract, county, or something else. Then, we have to turn that data into data that meshes with us.   

We use road network data sometimes. We used to build our own road networks, and now we use outside services who have data about traffic speeds. Road networks are really important to conceptualize something timewise. Sometimes we’ve thought about not just drive time but walk time or subway time. We analyzed some things in Tokyo once and we had to make a road network, if you will, that was based upon subway travel times. 

What types of content knowledge and skills did you use to evaluate, process, and analyze the data you gathered for your project? 

TP: I have a whole presentation, called the consulting toolkit, about the kinds of thinking that we have to go through to work successfully. People don’t necessarily know all the data that they’re going to need and they don’t necessarily have all the skills to solve a problem, so being able to pick things up quickly is really important.  

We’ve talked in our firm about letting the data guide you and being careful to let the data explain to you what it says. Our customers have questions and we need to be careful to not over interpret the data or over explain the data.   

We always have to look at the work that we’ve done and ask whether it makes sense. Sometimes it doesn’t make sense because we made a mistake. There are so many calculations involved in what we do, so we need to go back and see if we made a mistake. For example, William and I just got through with a particular city and there was a pocket of demand close to the core area. It didn’t make sense to us that it would exist there, so we went back and checked the calculations and discovered that there was a river creating a barrier. So, in this case, there was a geospatial reason.   

How did you apply geography and computer science to communicate the results of your project?  

Webster Pacific map showing a retail fashion client a comparison of the stores in which they and their competitors are located.

TP: This map is for a retail fashion company. They sell their products to wholesalers who resell the product to consumers. They wanted to know which stores (wholesalers) they should sell their product to, so we found out where the competitors were located. 

That’s the coloration of the dots. Every dot is a store and the reddest dots have the most competitors located inside of them. The black circle around the dots indicate stores where our client is located. Our client was in only one store where there were a whole bunch of competitors and they were in a lot of stores with smaller numbers of competitors. So maybe the client should be in the other red dots, whereas we might not want to be in these green stores as much. 

So this is an example about displaying our results. We try to think about the ease with which somebody who knows nothing about this could understand it. How hard are we making the viewer work to understand our results and how much mental effort do they have to expend? That’s an information design problem. It’s a bit of an art and a science. The best presentations are the ones that take the least effort to understand while still projecting the appropriate amount of complexity. You have to get the answer across with the least amount of work for the viewer. 

Reflecting on your work, how does it align with personal values and community or civic interests? 

TP: We work for clients who want to serve their customers and make money, and I appreciate helping our clients and being paid for doing that work. Are we saving the world with our work? Probably not, but we are supporting ourselves, our families, and our clients. There are certain clients that I wouldn’t work for because their values don’t align with ours.  

I feel good about our work. We have a great team that appreciates the adventure, discovery, and services that we give to our clients. We have school clients and we’re proud of helping them do a better job of educating their students.  

We get paid to do this really interesting work. I tell people I don’t travel around the world physically, but I do in my brain. We get to discover things and we learn – and that is part of the great wonder and joy of this work. We get to learn all the time. There are all sorts of discoveries happening in these realms that I think equate back to when these people were making antique maps and discovering the shape of California. We’re discovering the shape of things that exist. Where is our demand? Where are our competitors? Where should we go? Where should we advertise? So there’s discovery, and that’s fun.

I can’t use any of these programs but I understand the logic of all the work that we do, much of which is geocomputational. 

William, do you want to add anything? You have a background in geoscience. 

William Blomstedt (WB): I studied geography as an undergrad and then I did a master’s course in GIS so I came to the field that way. Tom, geospatially, you only started more recently doing geospatial stuff? The work evolved to geospatial analysis. 

TP: That’s right, seven years ago, one of our clients – a private school based in Manhattan – wanted to open up schools in cities all over the world and asked us to help them analyze cities as opportunities for locating new schools. And that’s what launched us. We evolved our geospatial capabilities for this particular client to help other clients and other schools think geospatially about new locations. We just helped a preschool in Washington DC and we also helped a private school think about why a location in San Francisco had not been performing as well. 

What is your educational background and how did you initially discover geocomputation and ultimately choose a career using geography and computer science? 

TP: My background was liberal arts. I studied economics and environmental studies at Williams and so I don’t know whether the career chose me or if I chose the career. It feels a little bit like it chose me. I think for William – he chose it, he was more curious geospatially early on.  

In the last five years, pretty much since we started geospatial analytics, I got interested in antique maps and that process of discovery. I think there’s a very real thread between our work and the kind of work that people did to think about exploration. For example, I have a map of California as an island from the 17th century. I think it was George Box who said, “All models are wrong, but some are useful.” Examples of things being wrong fascinate me because we see that every day, or we know our models are wrong, but the question is whether they are helpful. 

When thinking about geography, what specific background knowledge and conceptual ideas do you think are important and useful? 

TP: I think that the ability to think in the weeds and then to think about the forest is the most important skill that we have. To be able to go back and forth between details and the big picture. I don’t have a geographic education but I think that ability is critical to what we do every day.  

WB: When I was choosing to go to school to pursue geography, someone told me that you could take a GIS course that just teaches you how to use the program and do GIS. However, they advised me to go to a course where you do a thesis where you have to solve a problem, and GIS is the tool. Instead of just learning the tool, you need to use the tool to do something with it and think about the big picture, rather than just doing geographical analysis. 

When thinking about computer science, what specific background knowledge and conceptual ideas do you think are important and useful? 

TP: I think the willingness to accept that you don’t know everything and that there are things that we still learn. Repeatedly, we learn things and how to do things that we didn’t know before, so I think the willingness to accept that you don’t know everything is critically important.  

Can you mention any procedural knowledge that you think is particularly useful from the standpoint of either geography or computer science? 

TP: We see geography and computer science, or geospatial, like they’re melded together: geography and computer science and our use of programs.  

We use Excel and Google Sheets all the time because it’s how we get into the details and also get to the big picture. Now we’ve had a lot of young people join our firm and want to use Python instead of Excel. I’m not sure I would say that I have embraced it, but I can see the power of it. No matter how programmatic they get, it is important that our team understands how to come back to the larger questions and more conceptual ways of displaying what we’re doing.  

We’re fortunate in the sense that we are driven by our client and their strategy. Every client has a different definition of what is a customer to them and their market position. The priorities are the activities that support that market position and determine who is a customer, and how to spatially define a customer in a particular space. We often think about time. We do find that mileage is not good because a mile in New York City and a mile in Los Angeles are very different due to the time it takes people to get to and from things.  

What’s an example of a social, economic, environmental or other issue that you recently investigated in a project? 

TP: Our client wanted to find a location within a metropolitan area and the customers who would go to their store. Customers are only willing to travel so far. So we wanted to locate in a place where there’s more demand than competing supply for this company. We created a map to show demand and supply in the market. The basic point was to figure out where there’s more demand than supply. Geospatially, where does that exist? We took the demand and subtracted out the supply to get our answer. If all you were doing was looking at the demand, you’d get an answer that looks very different.  

What kind of questions did you ask and think about during this project? 

WB: It’s all about location, place, and interconnection. If we need to write a code or an algorithm, we do it to either iterate faster or to make a model. For a simple supply model, we can say the supply is all in one point. In a more complex model, we will say the supply is not exactly in that point but it’s around that point (e.g. within 10 minutes) and so we have to build a model which spreads that supply out and then computationally figure out where all the supply is.  

What types of data did you acquire to support your project, and are you able to identify up to three data sets that you use frequently? 

TP: We use Census data a lot.  

WB: American Community Survey. 

TP: We use lists of schools or stores on the web. Our client will also have data about their customers and information that we will integrate into our analysis.   

But Census data is by far the biggest one. For the census data, we deal with shapefiles. Sometimes we get data by Block Group, Census Tract, county, or something else. Then, we have to turn that data into data that meshes with us.   

We use road network data sometimes. We used to build our own road networks, and now we use outside services who have data about traffic speeds. Road networks are really important to conceptualize something timewise. Sometimes we’ve thought about not just drive time but walk time or subway time. We analyzed some things in Tokyo once and we had to make a road network, if you will, that was based upon subway travel times. 

What types of content knowledge and skills did you use to evaluate, process, and analyze the data you gathered for your project? 

TP: I have a whole presentation, called the consulting toolkit, about the kinds of thinking that we have to go through to work successfully. People don’t necessarily know all the data that they’re going to need and they don’t necessarily have all the skills to solve a problem, so being able to pick things up quickly is really important.  

We’ve talked in our firm about letting the data guide you and being careful to let the data explain to you what it says. Our customers have questions and we need to be careful to not over interpret the data or over explain the data.   

We always have to look at the work that we’ve done and ask whether it makes sense. Sometimes it doesn’t make sense because we made a mistake. There are so many calculations involved in what we do, so we need to go back and see if we made a mistake. For example, William and I just got through with a particular city and there was a pocket of demand close to the core area. It didn’t make sense to us that it would exist there, so we went back and checked the calculations and discovered that there was a river creating a barrier. So, in this case, there was a geospatial reason.   

How did you apply geography and computer science to communicate the results of your project?  

Webster Pacific map showing a retail fashion client a comparison of the stores in which they and their competitors are located.

TP: This map is for a retail fashion company. They sell their products to wholesalers who resell the product to consumers. They wanted to know which stores (wholesalers) they should sell their product to, so we found out where the competitors were located. 

That’s the coloration of the dots. Every dot is a store and the reddest dots have the most competitors located inside of them. The black circle around the dots indicate stores where our client is located. Our client was in only one store where there were a whole bunch of competitors and they were in a lot of stores with smaller numbers of competitors. So maybe the client should be in the other red dots, whereas we might not want to be in these green stores as much. 

So this is an example about displaying our results. We try to think about the ease with which somebody who knows nothing about this could understand it. How hard are we making the viewer work to understand our results and how much mental effort do they have to expend? That’s an information design problem. It’s a bit of an art and a science. The best presentations are the ones that take the least effort to understand while still projecting the appropriate amount of complexity. You have to get the answer across with the least amount of work for the viewer. 

Reflecting on your work, how does it align with personal values and community or civic interests? 

TP: We work for clients who want to serve their customers and make money, and I appreciate helping our clients and being paid for doing that work. Are we saving the world with our work? Probably not, but we are supporting ourselves, our families, and our clients. There are certain clients that I wouldn’t work for because their values don’t align with ours.  

I feel good about our work. We have a great team that appreciates the adventure, discovery, and services that we give to our clients. We have school clients and we’re proud of helping them do a better job of educating their students.  

We get paid to do this really interesting work. I tell people I don’t travel around the world physically, but I do in my brain. We get to discover things and we learn – and that is part of the great wonder and joy of this work. We get to learn all the time. There are all sorts of discoveries happening in these realms that I think equate back to when these people were making antique maps and discovering the shape of California. We’re discovering the shape of things that exist. Where is our demand? Where are our competitors? Where should we go? Where should we advertise? So there’s discovery, and that’s fun.

John D. Nystuen

Professor John D. Nystuen, Ph.D., 91, of Ann Arbor Michigan, passed away on July 2, 2022 at his long-time home on Olivia Avenue in Ann Arbor.

After graduating from Oroville High School in Northern California in 1948 he moved to Berkeley and the University of California, completing a Bachelor of Arts degree in Geography in 1953. Immediately after graduating, he finished ROTC training as a Second Lieutenant in the Army Artillery, serving two years at Misawa Airbase in Northern Japan. In 1955 he earned a Master’s degree and Doctorate in Geography from the University of Washington in Seattle. John’s professional career began in 1959 at the University of Michigan in Ann Arbor in the Department of Geography, and later he worked in the Taubman College of Architecture and Urban Planning. John educated a world of doctoral students. He was the chair for more than 70 Ph.D. students from around the globe. Many of his students comment on how much they learned from him and how supportive and caring they found him to be in their intellectual development. Indeed, Gwen notes how John often said that he had learned a lot from his students, as well. He was a master of the one-on-one educational experience. He implemented his belief in interactive educational interchange long before it became fashionable.

John was a leader not only in the mentoring arena but also in the research arena. As one of the first ‘space cadets’ in the quantitative revolution in geography, originated at the University of Washington in Seattle, John retained a lifelong curiosity not only about traditional geographic inquiry but also about the role of the geographer in studying evolving dynamical systems as applied both on the Earth and in the heavens above.

He published numerous books and articles with citations available in major citation indexing services. Many of his publications are archived in Deep Blue, the online persistent digital repository of The University of Michigan. He served in advisory capacities on academic boards specific to mathematical geography (first on that of the Michigan Interuniversity Community of Mathematical Geographers and subsequently on that of the Institute of Mathematical Geography).

In the early 1960s John and Gwen, his wife, met with the seven Sierra Club members who lived in Ann Arbor (out of the 40 who lived in Michigan). They began meeting regularly, going on outings, and working on conservation issues. John was active in recruiting students and faculty from his and related departments. By 1967 they had a large enough membership to become a local Sierra Club group and ultimately formed the state chapter in Michigan. Over the succeeding years, John continued his work on local and state issues — contributing to our local Natural Features Inventory and supporting Gwen in an amphibian survey in local ponds. John also contributed his photography and sketching skills to many local conservation efforts.

John is survived by his wife of 67 years, Gwen Nystuen, and their daughter, Dr. Leslie Ann Nystuen, M.D. [Peter Leopold], sister-in-law Gaile Hoffman [Augustus] of Oakland, California, and nieces and nephews in California, Washington, New Mexico, Canada and Australia.

Education: Bachelor’s degree in Geography: Geographic Information Science (San Diego State University)

The following profile was compiled by Jessica Embury (San Diego State University) for the Encoding Geography initiative. To learn more, visit: https://www.ncrge.org/encoding-geography/


Please describe your job, employer, and the primary tasks you perform in your position.  

I am a GIS Specialist at the City of Oceanside Water Utilities Department. I am directly responsible for coordinating the collection of data among various departments and teams and managing the data collected. I often automate tedious tasks in order to build efficient workflows and processes for the collection of data and presentation of information.    

What is your educational background? How did you initially discover geocomputation  and why did you ultimately choose a career that uses geography and computer science?  

I chose to pursue an education in GIS because I was interested in making a positive change in our natural environment. I had aimed to leverage GIS to strengthen my environmental studies and I had come to realize that it was extremely important to have a technical skill set. It was not enough to know how to make maps and I began to learn python coding. This is when I realized the importance of data design and I expanded my toolset by learning SQL. These skills could be applied to many different fields of study, and I utilize them daily in local government.   

When thinking about geography, what specific background knowledge and conceptual ideas are important and useful to know?  

Knowing the fundamentals of Geographic and Projected coordinate systems can be useful when handling data. This is a foundational GIS concept but can be more complex than some GIS professionals would like to admit.    

When thinking about computer science, what specific background knowledge and conceptual ideas are important and useful to know?  

Data design is key. The correct data types must be considered when attempting to integrate computer science with GIS programs like Esri software.   

What procedural knowledge is important and useful to know, from either geography or computer science?   

Data cleanliness is important and having standard operating procedures for the collection of that data can make the difference between having reliable or unreliable data.  

What is an example of a social, economic, environmental, or other issue that you have recently investigated in a project at work?  

I assisted the Homeless Outreach Team in developing a survey application to better identify homeless individuals who are qualified for assistance programs. The surveys are submitted to a database and have auto-calculated fields using SQL triggers to help create more usable and robust datasets so that decision makers are more informed.   

What types of questions did you ask and think about in your project? 

I was interested in identifying hot spots of homelessness within the city and why those areas are as such. Temporal scales were considered when designing the dataset in order to have a better snapshot of the current situation. Surveys older than six months are archived using scheduled scripts. Analysis of regional interconnectedness is ongoing, and many questions are beginning to arise, both geographically and programmatically.    

What types of data did you acquire to support your project? If possible, please identify up to three datasets you utilize most.  

We utilized zoning datasets to identify responsible agencies that are required to respond to homeless activity. Districting datasets were also utilized to assign volunteers to regions of the city with more homelessness during the homeless point-in-time count.   

What types of content knowledge and skills did you use to evaluate, process, and analyze the data you gathered for your project?  

While analyzing the survey data, it was imperative that null and ‘declined’ values were accounted for to not skew the statistics. The data, or lack thereof, had to be presented succinctly.   

How did you apply geography and computer science to communicate the results of your project?  

I created an Esri Dashboard for the Homeless Outreach Team to view the live data collected in the field, which allows supervisors to observe homeless statistics and track their team’s progress.  

Reflecting on your work, how does it align with your personal values and your community or civic interests?  

I want to do everything I can to make my community better. I believe I have the power to influence change when leveraging my GIS skills and can apply my geographic and computational expertise to a multitude of different issues.

Hsiao-Chien Shih

Education: PhD in Geography (San Diego State University, UC Santa Barbara), MS in Geographic Information Science (San Diego State University), BA in Geography (National Taiwan Normal University)

The following profile was compiled by Jessica Embury (San Diego State University) for the Encoding Geography initiative. To learn more, visit: https://www.ncrge.org/encoding-geography/


Please describe your job, employer, and the primary tasks you perform in your position. 

I am a data scientist at E Source, a utility consulting firm that helps clients in a data-science-as-a-service manner. Our main task is to reduce power outage risk. My job tasks include acquiring, exploring, extracting, and transforming geospatial (and sometimes time series) data, including remotely sensed imagery, elevation, land cover, and utility assets as inputs for data science and modeling. In addition, I compile and aggregate the output risk in a geographic data format.  

What is your educational background? How did you initially discover geocomputation and why did you ultimately choose a career that uses geography and computer science? 

I am a geographer and I have doctoral, master’s, and bachelor’s degrees in Geography. My initial discovery of geocomputation came from an introductory level GIS course during my undergraduate period. I kept taking other geospatial courses, including remote sensing and spatial statistics. I found my abilities in math and reasoning made geocomputation attractive. Besides, geographic information represents real-world big datasets that can be used to solve real-world problems. Thus, I aimed to work in this field for my career. 

When thinking about geography, what specific background knowledge and conceptual ideas are important and useful to know? 

I tend to emphasize the absolute and relative geographic locations of a phenomenon, and then I shift my attention to the associated spatial distribution and temporal dynamics. The spatial-temporal process always attracts me, and I am interested in the background mechanisms of the process. For example, the spatial-temporal processes of urbanization were my dissertation topic. 

When thinking about computer science, what specific background knowledge and conceptual ideas are important and useful to know? 

Programming skills are critical for handling large amounts of data iteratively. Machine learning and its associated applications are critical to the work I perform. With the understanding of various sources of data and their caveats, I compile data to create critical inputs for machine learning. Finally, cloud computing is critical for the current job market due to the nature of largevolume geospatial data.  

What procedural knowledge is important and useful to know, from either geography or computer science? 

Knowing how to handle (read/write) geospatial data is necessary. Understanding approaches to analyze raster, vector, or point cloud data significantly contributes to the current utility consulting industry. 

What is an example of a social, economic, environmental, or other issue that you have recently investigated in a project at work? 

My colleague and I regularly work to estimate and reduce power outage risks due to environmental effects. We monitor vegetation growth based on remotely sensed data around utility assets, and then provide feedback to our clients for prioritizing vegetation management. To accomplish this task, we need to know how to compile remotely sensed, elevation, and other sources of data for monitoring the environment. Thus, knowledge of remote sensing, image processing, geometry calculation, spatial analysis, and machine learning are necessary.  

What kind of questions did you ask and think about during this project? 

For the above task, we consider the spatial scale and resolution of multiple sources of data. It is important to know how to incorporate data across multiple scales and what each scale represents in terms of the data source. We often calculate the relative location between any two objects to understand the risk of power outage. Therefore, calculating geometry is necessary. In addition, we need to know how to compile these data programmatically and we need to know some graph theory to boost the computation speed. 

What types of data did you acquire to support your project? Please identify up to three datasets you utilize most. 

Multiple sources of data are often used in our projects, and most of the data are publicly accessible. First, utility data will be used to define the geographic coverage of territories, and samples will be generated from the proximity areas of the data. We also use multiple sources of remotely sensed data, including Sentinel-2 and NAIP, as well as elevation data, such as LiDAR and the national hydrology dataset. Recently, we started using commercial satellite imagery (e.g. Planetscope data). 

What types of content knowledge and skills did you use to evaluate, process, and analyze the data you gathered for your project? 

Several skills are critical. First, knowledge of remote sensing and associated image processing approaches are necessary. Specifically, image spectrum analysis and image preprocessing are helpful. Second, machine learning knowledge is another must-have skill for data preparation and data quality confirmation, including classification and clustering. Finally, cloud computing is a nice-to-have skill because we often handle humongous amounts of data (e.g. AWS Sagemaker and S3). 

How did you apply geography and computer science to communicate the results of your project?  Do you have a recent product or publication that you could share with us as an example? 

We usually use python and QGIS for data visualization, and we use python for data compilation. Specifically, we rely on open-source python libraries (e.g.gdal) to handle geospatial data and create big data tables. Machine learning classification and regression are applied to estimate outage risks. Then, we create web-based apps to visualize the risk of power outage for our clients. 

Here is the link to our publication: https://www.esource.com/001201rt0d/data-science-company-improves-vegetation-management 

Reflecting on your work, how does it align with your personal values and your community or civic interests?  

I often think about how my learning during my undergraduate and graduate studies can contribute to a better world, especially in urban areas. The knowledge of remote sensing, GIS, and geocomputation perfectly helps me achieve the goal of moving the world toward a decarbonizing future. I am glad that I can apply my knowledge in the utility industry.

Carmen Leedham

Education: B.A. in Geography (San Diego State University)

The following profile was compiled by Jessica Embury (San Diego State University) for the Encoding Geography initiative. To learn more, visit: https://www.ncrge.org/encoding-geography/


Please describe your job, employer, and the primary tasks you perform in your position. 

I work for the County of San Diego, Health and Human Services Agency in the Office of Business Intelligence. The office I work for is a support department that works with other offices within the Health and Human Services Agency, such as Aging and Independent Services and Public Health Services. The primary tasks I perform revolve around GIS. I create static maps, web maps, and perform geospatial analysis to answer questions posed by leadership and my coworkers. For example, I performed geospatial analysis to convert tabular data into spatial data to answer, “How many CalFresh recipients live in each district in the County of San Diego?”  

What is your educational background? How did you initially discover geocomputation and why did you ultimately choose a career that uses geography and computer science? 

The people I met during my education have been instrumental in the trajectory of my career and have been very important to me. I first came into contact with geocomputation after completing a cultural geography course at Grossmont College with Professor Mark Goodman. He told me what a career in geography might look like and he encouraged me to enroll in an “Intro to GIS” course. At first, I did not understand anything, but the professors were so helpful and they made time for their students. I never had any computer classes in high school or middle school so learning how to work with a computer was very new to me. 

About a year later, I applied for an internship with the County of San Diego, Health and Human Services Agency in GIS. From there, I started to learn important skills, like how to work in a professional office, how to email people, and how to communicate with people in a professional setting. I started to really like it and see a life for myself working in GIS for a local government.   

At the time, I was 18 or 19 and I was going through a lot – I had unstable housing and food insecurity. I wasn’t sure how I was going to make it day-to-day or month-to-month. I saw GIS as a path to achieve the things I wanted: stable housing and a little bit of fun money. From that point forward, I started thinking about how to get a career in GIS as quickly as possible. In May 2019, I completed the GIS technician certificate of achievement at Mesa College – the requirement to get an entry level job in GIS with the County of San Diego. In September 2019, I got a full-time job with the County of San Diego in the Land Use and Environment Group. Since then, I’ve been with the County of San Diego, moving up and honing my skills in GIS.  

When thinking about geography, what specific background knowledge and conceptual ideas are important and useful to know? 

I feel like geography – both physical and cultural geography – cannot be separated from GIS or geocomputation. The foundation of geospatial analysis builds upon cultural and human relation to place and space throughout time. Likewise, GIS builds upon physical geography and knowledge of our surroundings.  

I mainly focus on cultural geography and the socioeconomic conditions of people within the Health and Human Services Agency of the County of San Diego. So, with geocomputation, we run the risk of turning people, plants, and places into numbers or into commodities and binaries. Through geography, we can return people from numbers and binaries back into real life things that have special life circumstances and value to one another.  

Conceptually, an understanding of sustainability should be gathered prior to working in geocomputation. Our actions have consequences, both positive and adverse, and this is something we should take into consideration in our day-to-day interactions. Our work always revolves around the three pillars of sustainability: people, profit, and planet.  

When thinking about computer science, what specific background knowledge and conceptual ideas do you think are important and useful to know? 

I recommend starting with the basics like: What are hard drives? What are the different types of hard drives and what do they do? What is the central processing unit of a computer? What’s a good one or a bad one? How much memory does the computer or device have?   

Then, you need to understand different types of software. Think about your needs and what software can meet the questions posed by your research. From there, you have to learn how to use the software. What file type does the software use? How are these files opened in the software? How are they saved on your computer?   

When I started GIS, I went to buy a laptop and I thought, “Okay, I need something that can handle the amount of data I’m going to be running and the strain I’m going to be putting on my computer.” I had to look at things like core memory and plan accordingly, because there are times that your computer will be overworked.  

What procedural knowledge is important to know, from either geography or computer science, in your work? 

It is important to know how to isolate your question, so things like the scientific method can be helpful. You don’t need to follow it exactly, but it can help you identify methodology to solve the question. What information do I need to solve this problem? Does this information exist in the format I need and, if not, can I create this information or do I know someone that can assist me in gathering this information? 

From there, test your methodology. Be flexible because a lot of things aren’t going to work and you need a plan B, C, D, and so on. It’s very helpful to know people within your line of work so you can ask questions and be nudged along in the direction you need.  

Can you share a specific example of how you apply geography and computer science to analyze and solve problems related to important issues?  

Since March 2020, when the novel coronavirus entered the United States, the County of San Diego tried to get ahead of it. We had public health scares in the past, like the Hepatitis A outbreak, so we had a little bit of a framework. 

My office develops and maintains a publicly available web map application for locations with publicly funded hand washing stations and public restrooms targeted for use by individuals experiencing homelessness. The County of San Diego hoped to prevent the spread of COVID-19 by placing hand washing stations and portable restrooms in locations that have known homeless encampment sites.  

What kind of geographic questions did you ask and think about during this project?  

The Office of Business Intelligence did not have to decide where the washing stations would go, but we relied on spatial data about homeless encampments to show hotspots and clusters of people experiencing homelessness.  

Someone else using this data would say, “Let’s place a hand washing station on this street where there are a lot of people experiencing homelessness,” and from there, I would receive the name of the street that this hand washing station is on and other internal information, such as how long it will be serviced or problems with the station itself. I would then convert this tabular data into spatial data. Addresses are not spatial data because there are no latitude or longitude coordinates connected to them. These coordinates are necessary to perform geocomputation, otherwise, it’s just data on your computer.  

We ended up creating a public web map application. I published the data as a hosted feature service on ArcGIS Online and I update it every so often. I had to think about possible problems with sharing this data with a large audience. We didn’t know how many people from the public would be looking at this map and a lot of pings could cause the map to be slow or stop working. I had to think of these problems ahead of time because if this map were to go down then the public would ask questions.   

In doing this project, I had to understand the software I was working with and the data formats. I had to think about whether the public would have problems viewing the map, and whether the data was understandable and digestible to the audience.  

What types of data did you acquire to support your project? Please identify up to three data sets that you utilize the most. 

I frequently perform geocoding to assign latitude and longitude to an address using an address locator. An address locator consists of different road networks of polylines within an area. For example, SANDAG publishes a dataset called “roads_all” that contains road types, road names, and address ranges. The address locator matches the tabular address data to spatial data in the road network and then converts the tabular data into spatial data. 

Since we have so many geocoding requests, we work on building the best address locator to match with the most addresses in the least amount of time and with the highest accuracy. We use “roads_all” from SANDAG as well as a road network from ESRI. We also use TIGER/Line shapefiles from the US Census Bureau because sometimes people have mailing addresses outside of the County of San Diego. I combined these road network datasets to produce a composite address locator that I worked with daily for this project. I also used the point in time homeless count from the San Diego Regional Task Force on Homelessness as well as internal data sent by my coworkers in neighboring offices. 

What types of content, knowledge, and skills did you use to evaluate the project and analyze the data gathered for your project? 

Something I wasn’t prepared for was the amount of general skills, like Excel and Word, needed to perform day-to-day tasks. Communication is another huge part of my job, so I have to understand the needs of the project, the questions answered by the project, and how to provide deliverables to the customer. The customer could be one of my coworkers in an office or it can be the public. 

With the hand washing stations and portable restrooms web map, I needed to make sure that the data was always up to date and that the data could handle being updated frequently. I needed a huge understanding of ArcGIS Online and that suite of products. Another aspect was working with firewalls. I work in a secure network that the public cannot access, so I needed to get private data to the public and ensure that it met requirements to share with the public.   

More specific skills I used are geocoding, creating an address locator, creating web maps, and creating web applications. 

How did you apply geography and computer science to communicate the results of your project? Do you have a recent product or publication that you could share with us as an example?

The web map of hand washing stations and portable restrooms is on 211 San Diego and contains hand washing station icons and portable restroom icons. Using this map, you can enter an address to see where the nearest hand washing station or portable restroom is. You can click on an icon and get additional pop-up information.   

To create this map, I had to use Excel, bring the Excel spreadsheet into ArcGIS Pro, geocode the data set with my composite address locator, create a feature class in my geodatabase, and publish it online for the public to view. Once published on ArcGIS Online, the data is stored in the cloud and is referred to as a hosted feature service. I had to ensure the sharing capabilities were correct so other people – like students – can bring this data into their own maps. Then, I had to make sure that there were no technical problems on the backend which would make the map stop working.  

When reflecting on your work, how does it align with your personal values and your community/civic interests? 

I used to be a customer of the County of San Diego and I used to receive CalFresh. I saw how the County of San Diego helped me, I see how it helps other people who are in that situation, and I know that some good is being done. That is rewarding to me. The things that I care about are making sure that people are able to live well and thrive, rather than just survive and get by. It’s nice to know that there is a group of people working to make sure that the basic needs of our community are met, and that resources are available. 

For me, public web maps are key because we can show the public that there are resources available. People don’t always know what’s available to them and we need to share the work that we’re doing and what the County of San Diego provides. I like working for an organization that is helping people and making sure that things are working as they should be. It makes me feel good — like harm reduction is occurring.

Toward a Brighter Post-Pandemic World

I begin this year of my presidency feeling thankful. Thankful that I survived the pandemic (so far!) and thankful for the opportunity to serve my discipline at this level. So, before I write another word, I want to say thank you for giving me this opportunity. I did not imagine, indeed, could never have imagined becoming president of this Association when as a child my interest in geography began to develop. I am looking forward to working with the Council on matters of importance to geography and to the members of the AAG. I am looking forward to going to the regional meetings this fall and doing my part to support and encourage the work that the regions are doing. I firmly believe that as its regional divisions thrive, so will the whole Association.  

In this column, I’ll focus on the effect of the pandemic on us. I want to acknowledge here our three previous presidents who served their terms under the shadow of COVID-19, as well as our Executive Director Gary Langham who has only known the AAG during the pandemic. David Kaplan was there in March 2020, just as these changes had begun, writing a compassionate column warning of the threat, pointing out how well positioned geography is to help us understand the threat, and asking us to be careful ourselves and to look out for others. Amy Lobben served her term completely virtually, and Emily Yeh’s term was almost completely virtual. Their stewardship has meant that the AAG has not only survived the pandemic, but seized opportunities to re-envision its service to members.   

I’m beginning my presidency at a peculiar time in the AAG’s history. For the past two and a half years we’ve been living with a pandemic, forced by the extremely contagious novel coronavirus – COVID-19. This virus and our response to it have changed the way we live and work, the economy, and society, in fundamental ways, some of which we will only recognize in coming years. And these changes are not limited to the US. They are worldwide.   

Emergence from the pandemic has not been a smooth transition back to normal, probably because that pre-2020 normal does not exist anymore. We are now in what some call a new normal, and others the post-pandemic world. I wonder, is it true that we are post—pandemic, and if it is, what exactly does that mean? How has this experience changed what and how we think, as well as how we live our lives? How much of that change is good? How much of it do we need to undo? What has not changed and needs to change? What has changed but not enough, so that we still need to work on it? What has changed that we need to keep in its new form? I have a lot of questions.   

Emergence from the pandemic has not been a smooth transition back to normal, probably because that pre-2020 normal does not exist anymore.

Over the course of the last two and a half years I have been actively looking at these changes with the express aim of seeing what good I could extract. One might say, actively trying to find the silver lining in the mesoscale convective complex that is COVID-19. It is not an easy task, but I did not want to emerge from the pandemic with nothing positive to show for all of the chaos that it caused. Here is some of what I found. 

COVID-19 separated us from each other. Our first response to the virus was to isolate ourselves, either due to official lockdowns or by choice and concern. In that justifiable fear for our lives before vaccines became freely available, we withdrew, stayed home, worked from home, attended classes from home, and tried to play at home. For many of us this was fine. We took the opportunity to focus on family life, DIY projects abounded, selfcare ascended as a vital approach to our days. For many of us, though, the lockdown phase of the pandemic was hugely problematic. Many people could not stay home or lost their jobs because employers depended on us to show up, but we withdrew. Trying to work/teach/host/attend meetings online from an active home was difficult, sometimes embarrassing. And yes, sometimes, that home to which we withdrew was not a safe space. My silver lining (and I realized later, that of many others) is the weekly family Zoom meetings that my brother instituted. We are a large family living in several countries, thousands of miles apart from each other and we had the real fear that isolation forced by Covid would destroy our connectedness. The weekly Zoom meetings have helped to keep us connected even more tightly than we were before the pandemic began.   

What has changed that we need to keep in its new form?  What has changed but not enough so that we still need to work on it?  

We changed how we travelled and communicated. We greatly limited airplane travel and drove fewer miles, especially those who stopped commuting to work. Texts and phone calls and social media were no longer backed up by in-person social events or the daily meetings and conversations at work. Our annual meetings, where we met our colleagues, renewed friendships and collaborations, and shared our research, went virtual. And, despite the heroic attempts of our tech people, virtual spaces cannot compare to in-person for maintaining those vital connections. One—alas temporary—silver lining here was an immediate and significant effect on the levels of atmospheric pollution in major cities around the globe. In Los Angeles, where I “isolated” I have never seen such brilliantly blue skies except perhaps the day after a storm passed over. The pandemic showed us that we could substantially cut emissions of greenhouse gases if we were forced to. Another, more enduring, silver lining here is that as we are emerging from the crisis and able to again meet in person, we have also learned the value—especially for cost, and access—of maintaining a virtual option.   

COVID-19 negatively affected our academic units. One of my tasks as Vice President was to organize and host the Departmental Chairs’ Luncheon. As a part of preparing for the discussion, the group was polled for topics of interest. Advice on how to deal with the negative impacts of COVID-19 on their departments was the topic most often mentioned. Their concerns ranged from work overload and burnout to low faculty morale and the fear that the pandemic had forced structural changes, often bringing student and faculty and staff expectations into conflict. These underscored for me how negatively affected we have been by the pandemic and the urgent need to take steps to support our faculty and students in the wake of the pandemic. But the discussion around these issues also revealed to me how strong the desire is to come through this safely and to use what we have learnt to make stronger, more caring departments and indeed a stronger and more caring AAG. It is an opportunity for the AAG to become more relevant to its membership and to the broader community as we emerge from the pandemic.   

Changing For Good

This year as President I want to focus on bringing AAG to a sustainable post-pandemic state. I want us to take advantage of the new opportunities that have developed over the past two and a half years. I begin in this column by addressing a couple of the questions that I raised earlier.   

What has changed that we need to keep in its new form? 

My answer here would be our approach to communicating. For example, there are ways we can improve the experience of virtual meetings at AAG. We do not have to completely sacrifice our annual in-person meeting; however, we should continue to expand and improve our virtual (and hybrid) capacity to provide thoughtful and well-executed options for participation. AAG is already providing new yearlong opportunities for us to engage with each other through Professional Development webinars for leaders and early-career geographers, as well as the Summer Series specifically for students. I can foresee membership growth with simultaneous reduced carbon footprint from this win-win approach. 

What has changed but not enough so that we still need to work on it?  

There are other answers here, but I will say that our awareness of inequality has heightened, supporting actions that were already started within the AAG. It is no coincidence that some of AAG’s most valuable programming under the Rapid Response to COVID-19–for example, Bridging the Digital Divide and the equity and mental health aspects of the Graduate Summer Series–were also meant to address longstanding inequities within the geography discipline, itself a mirror of inequities in society. As I said in my nomination statement for this presidency, COVID-19 brought these inequities into more prominence: “The legitimate fear of infection has led to an abrupt change in the way in which society operates and communicates, exposing the realities of our inequality.” While the trio of diversity, inclusion, and representation has been a focus in the AAG, it remains a critical issue, and AAG still has work to do to ensure that geography as a discipline becomes inclusive and equitable. We need to continue to work on reducing inequality and to address racial, social and environmental injustice, in our discipline. And the way to do this is through increased diversity, inclusion and representation of under-represented groups. I was excited to read the JEDI framework document and look forward to the implementation of its recommendations.   

The way ahead. The pandemic was/is a disruption of immense proportions. However, we geographers are a resilient bunch and because of this we will extract from this experience the pieces that will help us shape ourselves into a bigger/better/stronger organization. We will emerge and thrive, becoming really post-pandemic. I look forward to helping us get there.
