SpongeGIS is a spatial decision-support platform for valorising landscapes by their potential for water retention. Upload your data, choose factors, and produce opportunity maps in minutes.
A scientific, open platform for researchers, river-basin managers, and consultants. Integrates global datasets with your local field data.
Bring your own SPU grid or generate it from administrative boundaries. Compute 20+ scientific factors per cell.
Pick goals, assign weights to factors, validate correlations, and aggregate with reproducible class binning.
Download opportunity maps as GeoTIFF, CSV, or GeoJSON. Use them directly in QGIS, ArcGIS, or any GIS workflow.
From defining a study area to downloading the final map — 10 clear steps.
Choose an administrative unit or upload your own polygon.
What hydrological challenge are you trying to address?
Source the input layers you need for the factors you plan to compute.
One free account per researcher — confirmed by your email.
Log in and start a new valorisation session for your study area.
SPU grid, rasters, shapefiles — validated automatically.
Run correlation, weight, aggregate, valorise — all in the browser.
