This dataset contains maps of the location and temporal
distribution of surface water from 1984 to 2018 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 3,865,618 scenes from Landsat
5, 7, and 8 acquired between 16 March 1984 and 31 December 2018.
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,
2000-2018) for change detection.
This Yearly Seasonality Classification collection contains a year-by-year
classification of the seasonality of water based on the occurrence values
detected throughout the year.
