Satellite Data | Study area | Specifications | Remarks |
Landsat (30 m) and ASTER (15 m) [71] | Gangotri glacier, Himalayas |
| Results led to the accurate identification of glacial lakes using the NDWI. Lake identification based on ASTER dataset is slightly more accurate than Landsat dataset. |
World View 2 (WV2) (2 m) [72] | Greenland Ice Sheet (GrIS) |
| The slush elimination process was not accurate, but it can be made accurately by fusing morphological procedures using edge detection with multi-threshold procedures (accuracy = 85.2%). |
