Zbiór danych Global Inland Water przedstawia śródlądowe zbiorniki wodne, w tym jeziora słodkie i słone, rzeki i zbiorniki.
W okresie GLS 2000 zidentyfikowano 3 650 723 km² wód śródlądowych, z czego około trzy czwarte znajdowało się w Ameryce Północnej i Azji. Największą część wód śródlądowych stanowią lasy borealne i tundra – około 40% całości. Dane wykazują silną korelację liniową zarówno ze zbiorem danych MODIS, jak i ze zbiorami danych o rozdzielczości 30 m w Stanach Zjednoczonych i Kanadzie. Błędy resztkowe wynikały głównie z sezonowości pokrywy wodnej, śniegu i lodu oraz chmur resztkowych.
Zbiór danych zawiera co najmniej 1 obraz dla każdej dostępnej ścieżki/wiersza Landsat WRS2.

The data exhibits strong linear correlation with both the\nMODIS dataset as well as 30-m resolution datasets over the United States\nand Canada. Residual errors were due primarily to the seasonality of water\ncover, snow and ice, and residual clouds.\n\nThe dataset contains one or more image for each available Landsat WRS2\npath/row.\n\nDocumentation:\n\n- [User's guide](https://lpdaac.usgs.gov/documents/1371/GFCC_User_Guide_V1.pdf)\n\n- [Algorithm Theoretical Basis Document (ATBD)](https://lpdaac.usgs.gov/documents/1370/GFCC_ATBD.pdf)\n\n### Bands\n\n\n**Pixel Size**\n\n30 meters\n\n**Bands**\n\n| Name | Pixel Size | Description |\n|---------|------------|----------------------|\n| `water` | meters | Water classification |\n\n**water Class Table**\n\n| Value | Color | Description |\n|-------|---------|--------------|\n| 1 | #fafafa | Land |\n| 2 | #00c5ff | Water |\n| 4 | #df73ff | Snow/ice |\n| 200 | #828282 | Cloud shadow |\n| 201 | #cccccc | Cloud |\n\n### Image Properties\n\n**Image Properties**\n\n| Name | Type | Description |\n|---------------------|----------|---------------------|\n| path | DOUBLE | Path |\n| pathrow | STRING | Path and row |\n| row | DOUBLE | Row |\n| water_class_names | DOUBLE | Water class names |\n| water_class_palette | DOUBLE | Water class palette |\n| water_class_values | INT_LIST | Water class values |\n\n### Terms of Use\n\n**Terms of Use**\n\nIntellectual property rights to this dataset belong to University of\nMaryland, Department of Geographical Sciences and NASA.
