What is an ASTER DEM?
The Terra Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator).
How do I create a DEM file?
There are two methods to obtain DEM data:
- Using DATASETS: If you know the name of the quadrangle or area, you can obtain the files individually.
- USGS GEOSpatial clearinghouse: http://www.usgs.gov.
- GeoCommunity: http://data.geocomm.com *
- MapMart: http://www.mapmart.com *
- ATDI: http://www.atdi-us.com.

What is DEM PDF?
Digital Elevation Model (DEM) is the digital representation of the land surface elevation with respect to any reference datum. DEM is the simplest form of digital representation of topography . DEMs are used to determine terrain attributes such as elevation at any point, slope and aspect.
What is the spatial resolution of ASTER DEM?
15 meters
ASTER has two telescopes, one for nadir-viewing and another for backward-viewing, with a base-to-height ratio of 0.6. The spatial resolution is 15 meters (m) in the horizontal plane. Each scene consists of 4,100 samples by 4,200 lines which corresponds to about 60 kilometers (km) by 60 km ground area.
