基于MAPGIS的DEM制作技术研究

Study of DEM drawing technology based on MAPGIS

结合具体的项目工程,主要以MAPGIS软件对DEM制作的过程和遇到的技术问题进行了探讨研究,比较分析了不同数据转换方式的差异,有效地实现了从DGN格式数据到最终DEM的生成,并在制作过程中优化了数据流程.

With a project, the drawing method were researched by MAPGIS and the other GIS software, and the author analyzed the difference during different data conversion. Furthermore,The author produce DEM from data of DGN format successfully, and make the process as effective as possible.
