LakeSat – Synergetic use of earth observation data for scientific analysis of inland water bodies

The LAKESAT project aims to develop an application routine for scientific analysis of inland water bodies. The routine enables the use of various sensor types with high spatial and spectral resolution to investigate water colour (i.e. water constituents such as chlorophyll, dissolved inorganic and organic sediments) as well as bathymetry and bottom coverage in shallow water areas.

Bottom coverage includes different type of sediments as well as fresh water macrophytes. The water colour simulator WASI forms the basis for the routine, which will be embedded in the ENMAP toolbox and will enable the synergetic use of sensors such as EnMAP, Sentinel-2, Landsat-8, HICO/CHESS, RapidEye, and WorldView-2).
The main goals of the project are:

  • Analysing water constituents quantitatively (chlorophyll a, coloured dissolved organic matter, suspended matter) and water turbidity using sensors with high spectral resolution (EnMAP, HICO/CHESS, Sentinel-2 and Landsat 8)
  • Mapping water depths and benthos coverages (sediment, submerged vegetation) in optically shallow water using sensors with high spatial resolution (RapidEye, WorldView-2)
  • Assessing ecology of different lake types using coupled reflectance-growth-models of submerged vegetation in shallow waters.
  • Deriving atmospheric parameters from Sentinel-3 data to improve data analyses of sensors relevant for inland waters.
