Google Earth Engine——该数据集为格陵兰岛冰原提供了15米的完整的陆地冰和海洋分类

This dataset provides complete land ice and ocean classification masks at 15 m for the Greenland ice sheet. Ice cover was mapped using a combination of orthorectified panchromatic (band 8) imagery from the Landsat 7 Enhanced Thematic Mapper Plus (ETM+), distributed by the USGS, and RADARSAT-1 Synthetic Amplitude Radar (SAR) amplitude images produced and distributed by I. Joughin at the Applied Physics Laboratory, University of Washington.

The Landsat imagery was acquired for the months of July through September in 1999, 2000 and 2001 (mostly 2000) and the RADARSAT imagery was acquired in fall of 2000.

该数据集为格陵兰岛冰原提供了15米的完整的陆地冰和海洋分类掩码。冰盖的测绘采用了由美国地质调查局分发的Landsat 7 Enhanced Thematic Mapper Plus（ETM+）的正交全色（波段8）图像和华盛顿大学应用物理实验室的I. Joughin制作和分发的RADARSAT-1合成振幅雷达（SAR）振幅图像。

Landsat图像是在1999年、2000年和2001年（主要是2000年）的7月至9月获得的，RADARSAT图像是在2000年秋季获得的。
