This dataset contains maps of the location and temporal
distribution of surface water from 1984 to 2020 and provides
statistics on the extent and change of those water surfaces.
For more information see the associated journal article: High-resolution
mapping of global surface water and its long-term changes
(Nature, 2016) and the online Data Users Guide.
These data were generated using 4,453,989 scenes from Landsat
5, 7, and 8 acquired between 16 March 1984 and 31 December 2020.
Each pixel was individually classified into water / non-water
using an expert system and the results were collated into a monthly
history for the entire time period and two epochs (1984-1999,
2000-2020) for change detection.
This Monthly History collection holds the entire history of water detection
on a month-by-month basis. The collection contains 442 images, one for each
month between March 1984 and December 2020.
