Abstract：High geometric correction precision of GF-2 is a prerequisite for its widespread application. In this study, the authors selected Fuzhou as an experimental area. The ground control points (GCPs) were measured by Beidou satellite navigation system (BDS) and GPS respectively in the experimental area, which were used for geometric correction of the GF-2 panchromatic (PAN) image. The rational function model (RFM) was corrected by block adjustment with ground measurement point. The authors validated control point accuracy, distribution, as well as correction method for GF-2 panchromatic image correction, and analyzed the potential application to GF-2 PAN imagery geometric correction. The results show that a few control points can eliminate geometric error of GF-2 PAN imagery system. Affine transformation can reach the highest correction precision among three correction methods. Plane root mean square error (RMSE) of GPS check points using affine transformation is 1.49m and plane RMSE of Beidou RTK check points using affine transformation is 1.51m. In the two measuring modes of Beidou, Beidou RTK precision can satisfy the demand of GF-2 PAN imagery correction. The results show that, with a few high precision control points using GPS and Beidou RTK, GF-2 PAN imagery can reach high geometric correction accuracy and satisfy the demand of practical application.
