数字地形模型的建立方法及其在林业中的应用

Method of the Digital Terrain Model Establishment and DTM's Application in Forestry

介绍了矢量数据转换为栅格数据的方法。以花溪地形为例,重点介绍了利用MAPGIS建立GIS数字地形模型(DTM)的方法。展望了数字高程模型在林业中的应用前景。

Method of converting vector data to grid data was described. Taking the geography of Huaxi as an example, the method of establishing DTM by using MAPGIS was descried in detail, and the application of DEM on forestry was prospected.
