长输管道选定线中Google Earth的应用

Application of Google Earth in route selection for long-distance pipeline

针对油气长输管道线路的初步选定线作业,结合大地测量学的相关知识,以理论结合实际的方式介绍了如何将Google Erath内的管道中线经过简易的椭球变换,将其转化为国家或者地方坐标系,以达到最终的使用目的。

Aiming at preliminary selection of oil and gas long-distance pipeline route,a new method that transforms the centerline of route in Google Erath into national or local coordinate system via simple ellipsoid transformation is introduced,based on the knowledge of geodesy. It is very promising in the practical applications.
