湄潭县官坎脚水库DTM的建立及在测量工程中的应用

The Foundation of DTM in Kanjiao Reservoir and It's Application in Survey Engineering at Meitan County

讨论了DTM的建立过程及在山区水利工程中的一些应用,比起原始的仅为生成等高线而建立的DTM具有了更为广阔的应用空间,使得测量数据的运用价值大为提高,在测量工程中具有一定的现实意义,供有关人员参考。

This essay discusses the founding course of DTM and the application of it in the irrigation engineering in mountainous areas. It provides a wider space for the application than the original DTM that be built only for forming contours. Also it has greatly increased the application value of the geodesic data, which shows some practical meaning in the geodesic engineering. It also provides references for people.
