FAQ

What is the spatial extent of individual HMA DEMs?
HMA DEMs cover portions of eleven countries. The products are created from DigitalGlobe Inc. satellite imagery and have a relatively small footprint, especially compared to NASA missions. Users can download a shapefile or .kml from the HMA ancillary file directory (... read more
