基于Google Earth数据制作数字化地形图的方法研究

Research on the Method for Produce Digital Map Based on Google Earth

摘要: 针对电力工程设计前期阶段大比例尺地形图资料收资困难的问题，提出基于Google Earth进行二次开发获取平面、高程数据，然后利用这些数据编制大比例尺地形图的技术与方法。

Abstract:  It is difficult to collect large scale topographic map in early stage for electric power engineering design. Aiming at this problem, a new method to mapping large scale topographic maps by using plane and elevation data obtained by Google Earth with secondary development was presented.
