in this dissertation, the two sides of basic terrain factor and complex terrain factor are investigated and implemented based on the basic concept of digital terrain analysis introduced.
本文在介绍数字地形分析基本概念的基础上,从基本地形因子和复杂地形因子两个方面进行了研究与实现。
we mainly analyse digital terrain, which includes the computation of basic terrain factor and the abstraction of terrain characteristics.
数字地形分析的内容主要包括基本地形因子的计算和地形特征的提取。
the computation of basic terrain factor mainly includes slope, aspect and so on.
基本地形因子计算主要有坡度、坡向等。
