• Water Transitions (1984-2018)

    The data show the total change in extent of permanent and seasonal surface water area, measured against a historical reference period. Change is either gain or loss. Total change in extent of surface water area is calculated by comparing the most recent five years of data against a five year reference period (2000-2004). Permanent water is defined as being present all 12 months per year. Seasonal water is defined as being present less than 12 months per year.

    The surface area measurements reported here have been extracted from the Global Surface Water Explorer (GSWE) developed by the European Commission Joint Research Centre and Google. A coastline mask has been applied to prevent ocean water being included in the data. The analysis applied a consistent algorithm to all 36 years of the Landsat and Sentinel observations.
