Paper Abstract

DEM (Digital Elevation Model) is a commonest basic data in different geospatial applications. It is one of the fundamental issues for geo-science to extract the different kinds of terrain's waving characteristic in DEM self-adaptively and automatically. This paper presented our research on the basic mathematical model for rupture terrain characteristic extraction with variable-scale method. After the rupture edge characteristic point is obtained, the irregular line of rupture edge is generated in Terrain Characteristic Hypergraph Relationship (TCHR) [1] method, then combined into rupture's region object. Through experiment about submarine grid DEM, the comprehensive terrain characteristic of rupture can be obtained accurately and effectively, and its result matched the submarine terrain precisely.
