利用DEM辅助判定地形类别的方法

摘要

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.%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∶10000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。
