资源三号正射影像和DEM制作及电力工程适用性分析

ZY-3 Orthophoto and DEM Data Process and Its Feasibility Analysis in Electric Power Engineering

文章主要阐述我国高分辨资源三号测绘卫星传感器产品级的数据处理与分析方法,包括基于立体像对和CORS像控点提取高精度的DEM,以及利用所提取DEM和像控点制作正射影像。本文针对所提出数据处理方法,以广州市作为试验区域,开展成果产品精度分析与验证。探讨资源三号卫星影像数据在电力工程应用可行性及适用性。

The paper mainly introduced the data process and analysis method about sensor corrected（SC） level images of China high resolution ZY-3 survey satellite,including the method of high precision DEM process using the stereo image and CORS image control points,and the method of orthophoto image process using DEM and image control points.And then it used Guangzhou as the test region,and had accuracy analysis and verification of products using the method it presented.Based on the results,it discussed the ZY-3 satellite image feasibility and applicability in electrical power engineering.
