The Most Detailed Map of Antarctica

The Reference Elevation Model of Antarctica is the first, high resolution terrain map of Earth's southernmost continent. This most accurate and complete elevation model of Antarctica is a joint effort from Ohio State University and the University of Minnesota. The map was constructed from hundreds of thousands of individual stereoscopic Digital Elevation Models (DEM) extracted from satellite imagery of Antarctica.

You can view the new REMA of Antarctica on the REMA Hillshade Viewer. The REMA Hillshade Viewer also includes a number of map layers that show the locations of research stations and other Antarctic facilities. The elevation model of Antarctica records the height of nearly the whole continent to within a few feet of accuracy. It therefore provides an amazing resource for mapping future climate change on Antarctica.

The model is available to download as a shapefile or as 8 meter, 100 meter, 200 meter & 1 km resolution DEM's. The download files and more information on how the model was constructed are available from the University of Minnesota Polar Geospatial Center's REMA.
