摘要:
当前越来越多的勘测设计单位承接境外电网工程，但是经常又收不到如地形图等基础资料，本文利用Google Earth提供的全球免费的地图影像平台，进行电网工程的优化设计，数据采集，生成断面图，排干定位，最后直观的显示出整个路径图，从而弥补了在国外勘测设计时基础数据的不足，同时也分析了采集Google Earth三维影像数据进行初步排干定位的可行性，提高了勘测设计效率[1]，对部分国内电网工程的勘测设计也有一定的借鉴作用。
At present more and more survey and design units undertaking foreign power projects often cannot receive basic information such as topographic map data. The global free map imaging platform provided by Google Earth is used to optimized design of power engineering, collect data, generate section and preliminary position, finally displays the path diagram which makes up for the survey and design of basic data in foreign countries. Meanwhile, it analyzes the practicability of preliminary position of 3D image data provided by Google Earth, it improves the efficiency of survey and design and can be used as a reference for part of domestic power projects’ survey and design.
