ICESAT-2 LASER ALTIMETRY DATA-GUIDED HIGH-ACCURACY POSITIONING OF SATELLITE STEREO IMAGES [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 Positioning accuracy is a key indicator that restricts the accuracy of satellite image mapping. Laser altimetry acquires surface height in decimeters or higher accuracy, providing high-accuracy topographic information for satellite photogrammetry.
