The European Commission's Joint Research Centre developed this new water dataset in the framework of the Copernicus Programme. This maps the location and temporal distribution of water surfaces at the global scale over the past 32 years and provides statistics on the extent and change of those water surfaces. The dataset, produced from Landsat imagery (courtesy USGS and NASA), will support applications including water resource management, climate modelling, biodiversity conservation and food security.

The Global Surface Water Explorer is a simple web mapping tool that shows all of the water datasets and allows users to navigate the globe visualizing the water datasets without installing any software. It also allows users to view the complete history of water detections over the 32 year period by clicking on the map. The tool is intended as a data viewer and does not provide any analytical features - if you would like to do your own analysis on the data then access the data using Data Download or Google Earth Engine.
Download of the datasets. If you are using the data as a layer in a published map, please include the following attribution text: 'Source: EC JRC/Google'. Currently all of the mapped datasets are available for download (i.e. occurrence, change, seasonality, recurrence, transitions and maximum extent). The water history datasets and metadata datasets will be made available in the near future.
