利用DEM辅助判定地形类别的方法

Method for Determining Terrain Classification using DEM

简要介绍了利用已有25 m或者30 m格网的DEM生成坡度图,对1∶10 000地形图的地形类别进行准确地划分,为准确地确定具体图幅控制成果精度范围、减轻一线技术人员工作量、提高作业质量及效率提供依据。

This article introduced briefly the use had 25 meter or 30 meter gratitude mesh DEM production slope charts, to 1：10,000 scale topographic diagram terrain category carries on the accurate division, for the accurate determination concrete map sheet control a- chievement precision scope, reduces a technical personnel work load, improves the work quality and the efficiency provides the basis.
