Study on the Planimetric Accuracy of ZY1-02E Satellite Remote Sensing Images
In order to further prove the applicability of the digital orthophotos produced by ZY1-02E satellite images for surveying and mapping geographic information,especially for realistic 3D construction,this paper carried out the digital orthophotos production ex-periment based on 25 ZY1-02E satellite images. The planimetric geometric accuracy of the satellite images was verified by mean square errors of the checkpoints on the digital orthophotos collected from different terrain types,such as flat land,hilly land,moun-tainous land and high mountain,and the comparison and qualitative analysis were carried out with other types of satellite images. The results show that the rectified image results meet the planimetric accuracy requirements of 1∶25000 scale topographic map.
