Aster digital elevation model over Amundsen Sea Embayment

A surface elevation data set over Pine Island Glacier and Thwaites Glacier. Surface elevation data set was retrieved by mosaicking individual ASTER digital elevation models derived from AST-L1A data acquired in Jan/Feb 2018 (freely available at https://search.earthdata.nasa.gov/) using the open-source Ames Stereo Pipeline (ASP)

本数据集为覆盖松岛冰川（Pine Island Glacier）与思韦茨冰川（Thwaites Glacier）的地表高程数据集。该数据集通过对2018年1月至2月获取的AST-L1A级数据衍生得到的单幅高级星载热发射与反射辐射计（ASTER）数字高程模型进行镶嵌拼接构建而成，所用AST-L1A级数据可于https://search.earthdata.nasa.gov/免费获取，处理过程采用了开源的艾姆斯立体管线（Ames Stereo Pipeline，ASP）。
