摘要
Abstract
Regular grid DEM had be widely used in the field of Engineering Survey and Hydrological Geology taking the advantage of simple data structure and calculation method. In the Overhead Transmission Line project, especial in the mountains, Generated 5m resolution DEM based on 1:10000 digital topographic maps, calculated the topographical factors as slopes and aspect, from the DEM depended on the Digital Terrain Analysis of GIS. This method had be proved to improve work efficiency.关键词
