数字地表模型构建方法的对比研究

Comparative Study of Digital Surface Model Construction

数字地形模型本质上是地形形状大小和起伏特征的数字描述。数字地表模型的构建有两种常用方法:三角网建模法和规则格网建模法。本文针对潘家田铁矿采用这两种建模方法进行地形表面的构建,并对其应用效果进行对比研究。

The nature of digital tea＇rain model is the digital description of the terrain features in shape, size and fluctuation. There are two commonly used methods for the construction of digital terrain model, the triangular mesh modeling and the grid modeling, which are used in this article to construct the surface model for Panjiatian Iron Mine and to make a comparative study of their application effects.
