基于规则格网DEM的坡度坡向分析研究

Analysis of Slope and Aspect Based on Regular Grid DEM

坡度坡向是描述地貌特征的重要参数,从晕渲图制作的角度出发,对不同数据情况、不同坡度坡向计算方法得到的坡度坡向进行对比,研究制图区域数据分辨率,地区类型对坡度坡向计算的影响。

Slope and aspect are important parameters for description of geomorphic features. This paper contrasted the calculation results of slope and aspect in different methods and different data from the perspective of relief shading map making, researched the effect of data resolution and type of cartographic regions on calculation results of slope and aspect.
