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

You are here

Context and objectives

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.

Project outcome

Expected scientific results

An atmospheric correction for aquatic application of very high resolution satellite imagery.
Very high resolution sediment concentration maps of Belgian ports and French rivers, improving knowledge on small scale sediment transport.
Evaluation and demonstration of remote sensing of small inland water bodies, with time series of concurrent Pléiades images and in situ measurements in the Grensmaas area.

Expected products and services

Availability of water quality products at 2.8m spatial resolution for inland waters and coastal sites.
Open source processor for aquatic use of Pléiades data.

Potential users are ocean colour scientists and water quality managers. Interested international users of the PONDER project outcomes are for example Ana Dogliotti (Argentina), Simon Bélanger (Canada).
