2000–2013年黄河源区阿尼玛卿山冰川表面高程变化数据集
Listed in ScienceDB
Description
本数据集应用2013年10月31日的TanDEM-X/TerraSAR-X双基站合成孔径雷达数据与SRTM (Shuttle Radar Topographical Mission)DEM (Digital elevation Model)进行差分干涉获得了阿尼玛卿山冰川的数字高程模型及近13年冰川表面高程变化数据集，数据集覆盖黄河源区阿尼玛卿山全部冰川，TanDEM数字高程模型的水平方向像素大小10m，高程误差小于2 m，高程变化数据集水平方向像素大小为30m高程精度为3.7 m。考虑到雷达图像的阴影与叠掩现象，高程变化数据集剔除了阴影和叠掩等不可靠区域。该数据集是黄河源区冰川变化及冰川水资源评估的重要基础数据，是后续该区域冰川体积变化研究的基础。
