MEaSUREs Greenland Ice Mapping Project (GIMP) Digital Elevation Model, Version 1

This data set consists of an enhanced resolution digital elevation model (DEM) for the Greenland Ice Sheet. It was constructed by combining ASTER and SPOT 5 DEMs over the ice sheet periphery and margin with AVHRR photoclinometry for the interior and far north, and calibrating the data to approximate mean ICESat/GLAS elevations from 2003 to 2009. See Greenland Ice Mapping Project (GIMP) for related data.本数据集包含一套适用于格陵兰冰盖的增强分辨率数字高程模型（Digital Elevation Model, DEM）。该数据集通过整合覆盖冰盖外围与边缘的ASTER与SPOT 5 DEM，以及适用于冰盖内部及极北区域的AVHRR光坡测量法（photoclinometry），并将数据校准至2003至2009年间ICESat/GLAS的平均高程近似值构建而成。 相关数据可参考格陵兰冰盖制图项目（GIMP）。
