How Satellite Earth Observation Can Help With Monitoring For The Water Framework Directive
Using knowledge about how certain substances, such as one of the main pigments of the phytoplankton (Chlorophyll a - Chl a) alter the colour of the water, these parameters can be derived from optial Earth Observation (EO) satellite sensors.
Water Insight provides monitoring services of Chl a based on EO data which is validated with in situmeasurements. Also the maps of WFD phytoplankton biomass status classes are created, by application of the WFD tresholds on Chl a as a proxy for phytoplankton biomass. The maps are made available in a portal, which allows to follow the lakes in time, zoom and download maps and time series.
- cheap and automated monitoring for under-sampled lakes, combined with targeted sampling in case of unexpected changes
- systems analysis, for which the spatial component is key
- evaluation of the spatial effect of measures taken to improve water quality for the WFD as input for spatial ecological models
