Error-reduced Digital Elevation Model Of The Qinghai-tibet Plateau Using Icesat-2 And Fusion Model

A new high-accuracy and error-reduced 30m DEM for the Qinghai-Tibet Plateau (HQTP30) has been developed using data from multiple sources, including LiDAR, SAR, and optical imagery. The HQTP30 is publicly accessible and can be used for a variety of scientific and societal applications.
