Software And Products

The WorldWater project gives users access to several products and software.


The WorldWater software package includes the following elements:

  • Surface Water Data Analytics Portal customised according to national priorities, with visualisation, statistical and analytical tools for an efficient utilisation of the WorldWater Surface Water Dynamics products by regional and national authorities
  • Free of charge and open source software toolbox, which can be integrated in existing national infrastructures such as national data cubes or other ICT infrastructures
  • A cloud facility with online access to the processing system
Software Operation Framework


WorldWater develops cost-effective methods for large-area and high-temporal monitoring of all water bodies (i.e. inland and coastal, lakes/reservoirs and rivers) in both their extent and volume. Surface Water Extent (SWE) is derived from the synergistic usage of optical and SAR imagery and integrating all observation from free and open satellite missions, i.e. Sentinel 1, Sentinel 2 and Landsat. The surface volume is inferred using Water Surface Elevation (WSE) estimates from radar altimetry observations such as Sentinel 3 SRAL, Jason 3 and Cryosat. The end result will be national maps showing surface waters for 4 consecutive years (2017-2020) for the chosen pilot countries.


The examples below showcase previous work done by partners involved in the WorldWater, illustrating the capabilities of the project consortium:

Monitoring surface water extent: Map of the southern shore of Lake Kariba, Zimbabwe, with 12-moth water occurrence frequency.

Monitoring Water Levels: Location of Sentinel-3 virtual stations for space-based water level observations. (Note: The yellow star indicates a virtual station near the Senanga gauging station.)
