A New Map of Global Islands

A New Map of Global Islands

Published by the AAG in 2019, this booklet makes a major contribution to understanding the physical and ecological geography of the Earth.

This publication maps hundreds of thousands of islands in greater detail than previous efforts. The islands range in size from continental mainlands to tiny islets smaller than a fraction of a square kilometer. The work was done at a very fine spatial resolution, and the shorelines and islands were mapped from hundreds of 2014 Landsat images.

The publication also describes an elegantly simple tool, the Global Island Explorer, which was designed as a window for users of the data. The Global Island Explorer is an online visualization and query tool, which allows anyone with an internet connection to explore any of the world’s islands in an easy to use app.

The work was done in a public/private partnership between the U.S. Geological Survey (USGS) and Esri, and was commissioned by the Group on Earth Observations (GEO) as part of an intergovernmental protocol called the Global Earth Observation System of Systems (GEOSS).
