基于Google Earth的输电线路选线三维场景研究

Three-dimensional Scene Study of Route Selection for Transmission Line Based on Google Earth

高质量的地形图是做好输电线路选线的重要前提,但传统的地形图简单且往往陈旧,商业化3S技术的数据价格昂贵且周期长.研究了通过Google Earth平台,结合GIS工具和KML语言和建模软件,建立输电线路选线用三维场景的方法,并通过相应例子验证了该方法的正确性.

Good quality of topographic map is an important premise of route selection for transmission line. However, traditional topographic map is simple and often obsolete; the commercialization data of 3S technology is expensive and long cycle. In this article, through Google Earth platform combining with the geographic information system （GIS） tools, KML language and modeling software, a method of three-dimensional scene for route selection of transmission line is established. Finally, the correctness of this method is verified by a case study.
