Verification of ZY-3 Satellite Imagery Geometric Accuracy Without Ground Control Points.
IEEE Geoscience and Remote Sensing Letters(2015)
摘要
The Ziyuan-3 (ZY-3) satellite was designed to satisfy 1:50000 scale mapping requirements. This study uses 556 images obtained by ZY-3, from June 1 to October 31, 2013, covering an area of 3 500 000 km 2 in midwestern China. A total of 900 check points measured by a global positioning system were also used to conduct the planar accuracy verification. The experimental results show that the ZY-3 nadi...
