Water monitoring

Water quality, extent and pollution in lakes, reservoirs, rivers and coastal waters, from optical, hyperspectral, thermal and SAR imagery.

Parameters

Turbidity	FNU	Optical
Total suspended matter	g/m³	Optical
Coloured dissolved organic matter	m⁻¹	Hyperspectral
Transparency (Secchi depth)	m	Optical
Surface temperature	°C	Thermal
Water extent	ha	SAR, optical
Oil and floating matter	Detection	SAR, optical

01
Quality maps
Parameter maps per date, calibrated with in-situ samples where they exist.
02
Algal blooms
Blooms and cyanobacteria flagged in reservoirs, lakes and bathing waters.
03
Reservoirs and lakes
Surface area per date; volume where bathymetry is available.
04
Floods
Flood extent through cloud and at night.
05
Pollution
Oil slicks, outfall plumes and floating debris at sea and along the coast.
06
Coast and sediment
Shoreline position, erosion and river sediment plumes.
07
Reporting
Indicators for Water Framework Directive and bathing water reporting.

01
Monitoring
Each water body on a fixed schedule, with alerts on blooms and pollution.
02
Single study
A baseline, an event, or a history rebuilt from the archive.
03
Integration
Time series and alerts into your monitoring system by API.
