The evaluation of geometric accuracy of high-resolution satellite images (HRSIs) has been\nincreasingly recognized in recent years. The traditional approach is to verify each satellite individually.\nIt is difficult to directly compare the difference in their accuracy. In order to evaluate geometric accuracy\nfor multiple satellite images based on the same ground control benchmark, a reliable test field in Xianning\n(China) was utilized for geometric accuracy validation of HRSIs. Our research team has obtained multiple\nHRSIs in the Xianning test field, such as SPOT-6, Pleaides, ALOS, ZY-3 and TH-1. In addition, ground\ncontrol points (GCPs) were acquired with GPS by field surveying, which were used to select the significant\nfeature area on the images. We assess the orientation accuracy of the HRSIs with the single image and\nstereo models. Within this study, the geometrical performance of multiple HRSIs was analyzed in detail,\nand the results of orientation are shown and discussed. As a result, it is feasible and necessary to establish\nsuch a geometric verification field to evaluate the geometric quality of multiple HRSIs.
