Welcome to SpongeGIS
SpongeGIS is a decision-support tool designed to assist planners, researchers, and policymakers in identifying optimal locations for implementing Natural Water Retention Measures.
The application offers a multi-scale spatial analysis environment to develop Opportunity Maps that highlight areas where nature-based solutions can enhance landscape water retention.
Key Features
- European-scale mapping of areas with potential for NWRM implementation
- Custom data uploads and analysis at user-defined resolution
- Targeted recommendations for drought, flood mitigation, or ecological restoration
- Interactive selection of suitable NWRM types based on local conditions
- Preliminary assessment of the hydrological effects expected of selected measures
About Opportunity Maps
Opportunity Maps (OMs) identify spatial zones where the need to improve water retention is most significant and where water retention measures are likely most effective.
Based on GIS data- such as land cover, topography, soil types, and hydrology, OMs help visualize areas where implementing NWRMs would be most beneficial. Using landscape characteristics such as climate, slope, soil permeability, and location within the catchment (e.g., river valley, river channel, or upland), the SpongeGIS application suggests the most appropriate NWRM types for each area.
Explore the Modules
The SpongeGIS application includes five core modules:
- General Opportunity Maps: Mapping general water retention opportunities at the European scale
- Local Opportunity Maps: Detailed local-scale analysis using user-supplied data
- General NWRM Hints: General maps with suitable NWRM suggestions for different European regions
- Local NWRM Hints: Tailored NWRM suggestions based on local-scale analysis
- Effect Assessment: Assessment of the expected hydrological impact of selected NWRMs
Currently, two key components are being consulted:
- A prototype web application for mapping the needs for Natural Water Retention Measures (NWRM);
- A list of landscape descriptors (factors) used in the application for landscape valorization.
