Extraction and Application of Water System and Physiognomy Morphological Characteristics Based on DEM in ArcGIS Environment

Abstract:

The Ms 7.0 Lushan earthquake triggered thousands of landslides. The main purpose of this paper is to present the use of the ASTER GDEM data, an incomplete landslide triggering factors of the M7.0 Lushan earthquake of China based on the ArcGIS platform and the DEM (Digital Elevation Models) technology. The sources of DEM are various. This paper discusses the prevalent DEM data source-ASTER GDEMs characteristic and applying GDEM data on extraction of water system and terrain characteristics of geological disasters using ArcGIS Hydro Tools package. A comprehensive quantitative analysis of the terrain parameters are performed such as elevation, slope, contour, drainage pattern, and thematic maps of geology and geomorphology lineament. These parameters are required as input to applications such as landslide susceptibility analysis.
