| 摘 要： | 数字高程模型（DEM）是一种常用的三维地形建模数据模型,三维地形的数字分析主要是针对DEM模型的。由于三维地形一般是随机起伏的,准确地求解表面积具有一定难度。经研究采用递归算法来求解切实可行,而且算法简单直观,准确性较高。经过验证比较,该算法具有较高的实用价值。

| Abstract: | DEM is one of commonly used 3D terrain data models,and 3D terrain＇s digital analysis is mainly made on DEM.As 3D terrain is usually random and undulating,it is quite difficult to calculate surface area accurately.It is feasible to solve through recursive algorithm for it is simple,intuitive and more accurate.Such algorithm is highly practical through verification and comparison. |
