Production of topographic models by remote sensing data - Digital Elevation Model

Abstract

This study sought to produce topographic maps of the first edge, which is part of a mountainous region extending over a large area estimated at (8450) square kilometers, the study area constitutes about (2952) square kilometers, and using remote sensing data The 30-meter Digital Elevation Model produced by NASA, using spatial analyst tools in GIS software, produced a contour map and a gradient map Slope, the Aspect Direction Map, and the Tilt Shadow Map Hill shade .
