Validation and Analysis of the Antarctic Digital Elevation Models Based on Airborne Altimetry——A Case Study of Thwaites Glacier, West Antarctica
Based on the IceBridge airborne altimetry data collected over Thwaites Glacier, West Antarctica, the accuracy of ICESat satellite altimetry data and four widely used DEMs of Antarctica, i.e., JLB97 DEM,RAMPv2 DEM,ICESat DEM and Bamber 1 km DEM were validated and analyzed. The results show that both...
