Abstract
As the first civilian high resolution stereo mapping satellite in China, the ZY-3 satellite can obtain high-precision terrain data efficiently and quickly, which has broad application prospects. In order to verify the application effect of the ZY-3 data in electric power engineering survey, this paper selects a transmission line project and a wind farm topographic mapping project as the experimental areas. The elevation accuracy of the ZY-3 satellite products is evaluated. Compared with the accuracy of STRM DEM, the results show that the accuracy of ZY-3 satellite data is better than STRM DEM, which can play a good auxiliary role in the electric power engineering survey and design stage.
