EOMAP

EOMAP is a private company in the field of Earth Observation, located in Seefeld Castle, Germany. It was founded in 2006 as a spin-off from the German Aerospace Centre (DLR). The company draws information about inland water and coastal environment worldwide from satellite imagery.[1]

This information includes water quality parameters and water depth. are relevant for nature protection (GBR), hydrography (IHR), or environmental assessment.

EOMAP analyses water quality by using remote sensing data. In 2018, UNESCO launched the World Water Quality Portal using EOMAP data. The portal provides information on freshwater quality, including parameters, such as Chlorophyll-a, water surface temperature, harmful algal blooms (HAB) or turbidity. [2] [3] The UNESCO Water Quality portal was further developed into eoapp[4] AQUA, a web tool for water quality analysis.

Turbidity is particularly relevant for hydropower activities, serving as a proxy for sedimentation [5]. In 2022, Reuters built its digital story "Starving the Mekong" on EOMAP turbidity data.[6][5]

Shallow water mapping

[edit]

Furthermore, EOMAP has specialised in Satellite-derived bathymetry (SDB), a technology for mapping shallow waters from space. SDB derives information on water depth from satellite sensors. It is known to be a cost-effective solution to map large areas in coastal regions or for survey planning by other methods.[7] Among others, SDB is used for hydrographic surveys.[8] The United Kingdom Hydrographic Office (UKHO), for example, has incorporated EOMAP SDB into their hydrographic charts.[8] The company has also provided SDB to help enforce international Sea Law in the South China Sea.[8]

In the Horizon Europe innovation project "4S", eoapp SDB-Online, a web application to create high-resolution bathymetry charts, was validated in 10 test sites.[9]

Technology

[edit]

For generating environmental information, EOMAP uses public satellite imagery from ESA[4] or NASA, but also that of private providers, such as Planet Labs, Airbus or Maxar Technologies. The company's physics-based technology is footing in the inversion of the Radiative Transfer Equation. It follows the sunlight's path from the water surface or seafloor back to the satellite sensor.[10][11]

Awards

[edit]

EOMAP holds international awards, such as the Copernicus Masters[4], the Cassini Maritime Prize by EUSPA for its web app "Eyes on Plastic" for detecting plastic and marine debris in water[12], or the Bavarian Innovation Award 2022 for SDB-Online.[13]
