Google Earth Engine—该数据集提供了格陵兰岛冰盖的完整的15米分辨率的图像，该图像来自1999年至2002年的Landsat 7 ETM+和RADARSAT-1 SAR图像

This dataset provides a complete 15 m resolution image mosaic of the Greenland ice sheet derived from Landsat 7 ETM+ and RADARSAT-1 SAR imagery from the years 1999 to 2002. The methods include a combination of image cloud masking, pan sharpening, image sampling and resizing, and image coregistration. Please see Howat, 2014 for more information regarding processing methods.

Note

• Users of GIMP DEM or GIMP 2000 Image Mosaic images may find it helpful to mask out areas outside of the Greenland coastline using the corresponding 15 m ocean mask image Greenland Ice Mapping Project (GIMP) Land Ice and Ocean Classification Mask,
• The SAR data are distributed at 20 m resolution. Data were up-sampled through bilinear interpolation to 15 m to match the resolution of Landsat band-8.

General documentation

该数据集提供了格陵兰岛冰盖的完整的15米分辨率的图像马赛克，该图像来自1999年至2002年的Landsat 7 ETM+和RADARSAT-1 SAR图像。这些方法包括图像云遮蔽、平移锐化、图像取样和大小调整以及图像核对的组合。关于处理方法的更多信息，请参见Howat, 2014。

备注

GIMP DEM或GIMP 2000图像马赛克的用户可能会发现，使用相应的15米海洋掩码图像格陵兰冰图项目（GIMP）陆地冰和海洋分类掩码来掩码格陵兰海岸线以外的区域是有帮助的。
SAR数据以20米的分辨率分布。数据通过双线性插值被上采样到15米，以匹配Landsat band-8的分辨率。
