利用MATLAB实现DEM可视化方法研究

A Visualization Method of DEM Based on MATLAB

随着社会生产对数字化地图,特别是数字高程模型(DEM)产品需求的日益增加,如何高效实现DEM的可视化已成为很多工程技术人员追求的目标。笔者尝试用MATLAB软件实现这一目标,并取得成功,所用方法使得DEM可视化过程变得更为简单、高效。

Along with the increasing social demand of digital map, especially DEM product, how to realize DEM visual- ization fast and efficiently has become the target of many en- gineering and technical personnel. This paper succeeds to use MATLAB software to achieve this goal. It proves that the method makes DEM visualization process more simple, more efficient and have more value for popularization.
