Radiometric and geometric characteristics of Pleiades images
Space Adjustment Restitution Georeferencing Radiometric
2014/12/4
Pleiades images are distributed with 50 cm ground sampling distance (GSD) even if the physical resolution for nadir images is just 70 cm. By theory this should influence the effective GSD determined b...
A New Method for Geometric Quality Evaluation of Remote Sensing Image Based on Information Entropy
Image Quality Information Entropy Geometric Accuracy Uncertainty Image Rectification
2014/11/28
Geometric accuracy of the remote sensing rectified image is usually evaluated by the root-mean-square errors (RMSEs) of the ground control points (GCPs) and check points (CPs). These discrete geometri...
