Geo Portal: interactive water quality maps
Water Insight Geo Portal is an easy to access web portal for water quality data. The Geo Portal contains water quality maps based on satellite data and and can be used to automatically upload WISP-3 in-situ data. The satellite based maps provides the high spatial resolution and the overview that laboratory studies usually lack. Furthermore, Geo portal allows you to create time-series of water quality specific for the water surface of your interest.
The services in Geo portal are based on spectral information of upwelling light from the water surface. Based on sound university research at the Institute of Environmental Studies (IVM, VU University Amsterdam) and others, know-how and techniques have been developed to determine the concentrations of water quality parameters from this spectral inforation with high accuracies.
Map subjects
Geo Portal-waterquality maps provides maps for larger water bodies under open weather conditions, with the distribution of:
- concentration of Chlorophyll in the water as proxy for algal biomass;
- concentration of Phycocyanin in the water as proxy for cyanobacterial biomass;
- concentration of suspended sediments (TSM);
- concentration of Coloured Dissolved Organic Matter (CDOM);
- water transparency, not only over PAR but also for separate spectral bands;
- Secchi Disk depth;
- occurrence of floating layers of cyanobacteria.
Application
Geo Portal-waterquality maps can be used for:
- Visualisation of water quality data in overview maps
- Gaining insight in the water surface of your interest by creating time series
- Combining point source and overview water quality data
