GLaSS: Global Lakes Sentinel Services

Lakes are important ecosystems providing many beneficial goods and services, but they are under significant pressure from agriculture, economical development and climate change. Monitoring changes in the ecological status of lakes is an important part of water resource management. Optical remote sensing techniques can provide water quality information at the high spatial and temporal resolution required for monitoring.

The upcoming ESA satellites Sentinel 2 and 3 will provide unprecedented monitoring capabilities for inland waters thanks to the high overpass frequency of S3 and the high spatial resolution of S2. However, the large amounts of data they will produce also pose a number of challenges: systems are needed that allow to ingest, archive, process and distribute these data efficiently. To be turned into information useful for water management, the large quantity of data also requires new methods of data mining and aggregation.

The GLaSS project will develop such a prototype enhanced service infrastructure for S2 and S3 data to make them accessible to a larger user community in a harmonised and user-friendly way. Particular focus will be put on adaptation of water quality algorithms to S2 and S3 data, and on the development of user-relevant value adding services.

The quality of the GLaSS system and its products will be ensured by testing it against simulated datasets, and by validating the products through a number of field studies and demonstration cases. The global case studies will demonstrate the applicability of the GLaSS system to very different lake types and management questions.
