Exploiting very high resolution satellite imagery for coastal and inland water monitoring  (PONDER)

Programme STEREO 3
Contract SR/00/325
Objective European directives require monitoring of inland and coastal waters, which is costly using in situ measurements and infeasible using typical satellite sensors. PONDER will develop an atmospheric correction and processor for aquatic use of very high resolution Pléiades data that will be validated using autonomous data.

Time series of images will be used for specific applications: sediment transport in Belgian ports, and monitoring of a wide range of water bodies in the Grensmaas area. Feasibility of algal bloom detection in inland waters using Pléiades will be assessed, using concurrent satellite imagery and in situ measurements during such a bloom event.

Method An image-based atmospheric correction algorithm will be developed for Pléiades water applications (based on earlier efforts for Landsat-8 and Pléiades data). The atmospheric correction will be integrated in an open source processor.

Pléiades imagery will be acquired concurrent with autonomous in situ measurements and planned in situ campaigns, to evaluate the processor performance and develop new applications.

In situ measurements in inland water bodies will include a.o. pigment analysis and light attenuation and turbidity measurements.
