Accuracy assessment of DSM in mountainous forest areas generated from GF-7 stereo images assisted by ATLAS/ICESat-2

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Abstract. The successful launch of the GaoFen-7 (GF-7) satellite has made it possible to achieve sub-meter-level three-dimensional mapping. However, most current studies focus on accuracy evaluating of GF-7 stereo mapping in bare land, and less on its performance in mountainous forest areas.
