Monitoring spatial variation of relief for determining morphometric terrain variables from SRTM data.

7.1.2 Abstract

The Shuttle Radar Topography Mission (SRTM) is an international research effort that obtained digital elevation models on a near-global scale from 56^∘ S to 60^∘ N to generate the most comprehensive high-resolution digital topographic database of the Earth in 2000, prior to the release of ASTER GDEM in 2009. However, SRTM uses RADAR observations to construct the digital elevation model (DEM) while ASTER uses stereo imagery and photogrammetric techniques to extract the DEM. The DEM obtained in the computational practice is used to determine ...
