Extracting Topographic Structure of Lanhe watershed from Digital Elevation Model 基于数字高程模型的岚河流域特征提取
Algorithm to generate digital elevation model is studied based on random fractal. 本文研究了基于随机分形的数字高程模型算法。
The water levels and water volumes of the lake in different periods were calculated by using a digital elevation model created by the topographic map. 利用数字高程模型求取易贡湖各时相的水位与水量。
