Water Quality

The Water Quality thematic app provides key parameters of water quality measures, such as: chlorophyll-a, total suspended solids and colored dissolved organic matter based on organic absorption and surface water temperature.

This service has been generated by EOMAP’s proprietary water quality processor Modular Inversion and Processing system (MIP). This processor includes sensor independent state of the art algorithms for adjacency correction, coupled atmospheric in water retrieval considering all bidirectional aspects from extreme clean to extreme turbid case 2 waters in a physically correct approach.

The Water Quality service is currently available for 2 regions:

• Niger River
• Red River

In order to get started with the Water Quality service, you can read the documentation and the service pricing.
