The composites include the Normalized Difference Water Index (NDWI), derived from near-infrared bands and reflecting liquid water content. Data is from USGS and is now deprecated, replaced by LANDSAT/LE07/C01/T1_ANNUAL_NDWI. The dataset is composed of all images within each year, with the most recent pixel as the value, and is in the public domain.\n"]]
