Download Digital Elevation Model 

A digital elevation model (DEM) is a representation of elevation data to represent terrain. A global DEM refers to a discrete global grid. DEMs are used often in geographic information systems, and are the most common basis for digitally produced relief maps. 

The digital elevation model (DEM) is considered among the data sources used in scientific research. It is also a source for the production of several types of data: slope map, aspect map, elevation map, contour lines, watersheds … 

Global Digital Elevation Models are available freely on the Web with spatial resolution 10m,12.5m, 30m and 90m. 

In this article I will show you how to download Digital Elevation Models with spatial resolution 10m, 12.5m and 30m and how to Extract Digital Elevation Model from Google Earth.
