摘要
以铜仁市滨江旅游大道为例,介绍利用ArcGIS软件生成TIN的方法。应用结果表明,该方法可以高效地利用现有的纸质地形图和矢量地形图等生成坡度图、坡向图,对地形分析进行量化和分析,并为城市规划、国土整治等行业提供数据依据。该方法不需要投入大量的设备,成本低,速度快,值得大力推广使用。
Take an example of binjiang tour road in Tongren, a method of constructing TIN using geographical Information System(GIS)software is introduced. The results show that: based on existing papery topographic maps and digital topographic maps, slope maps and aspect maps can be high efficiently acquired to quantize and analyze the terrain.
