AAG 2017 Featured Theme

Uncertainty and Context in Geography and GIScience: 
Advances in Theory, Methods, and Practice

AAG Annual Meeting, Boston, April 5-9, 2017

Kernel Activity Space map by R. Peterson; C. Browning; K. Calder; T. HawthorneUncertainty and context pose fundamental challenges in geographic research and GIScience. Geospatial data are imbued with error (e.g., measurement and sampling error), and understanding of the effects of contextual influences on human behavior and experience are often obfuscated by various types of uncertainty (e.g., contextual uncertainties, algorithmic uncertainties, and uncertainty arising from different spatial scales and zonal schemes). Identifying the “true causally relevant” spatial and temporal contexts that influence people’s behavior and experience is thus also challenging, since people move around in their daily lives and over their life courses and experience the influences of many different contexts. To generate reliable geographic knowledge, these uncertainties and contextual issues need to be addressed.

Call for Papers

Density map by M-P KwanThis theme within the 2017 AAG Annual Meeting will explore research frontiers and advances in theory, methods, and practice that address the challenges of uncertainty and context in geography and GIScience. We welcome papers from all disciplines, subfields and perspectives (e.g., geography, public health, sociology, transportation, urban studies, etc.).

Topics may include but are not limited to:

  • Uncertainty and context: advances in theory and methods
  • Human mobility and contextual uncertainties
  • Uncertainty and error assessment
  • Social networks as individual and social context
  • Error propagation and modeling
  • Quality of geospatial data
  • Big data, algorithmic uncertainties, and algorithmic geographies
  • The uncertain geographic context problem (UGCoP)
  • The modifiable areal unit problem (MAUP)
  • Advances in the conceptualization and assessment of the neighborhood effect
  • Improving assessments of exposures to physical and social environments and health
  • Exposure monitoring utilizing real-time interactive GPS/GIS methods

  • Cumulative contextual influences over the life course
  • Uncertainty in spatial pattern detection
  • Incorporating uncertainty in spatial modeling
