Using knowledge about how certain substances, such as one of the main pigments of the phytoplankton (Chlorophyll a - Chl a) alter the colour of the water, these parameters can be derived from optial Earth Observation (EO) satellite sensors. Water Insight provides monitoring services of Chl a based on EO data which is validated with in situmeasurements. Also the maps of WFD phytoplankton biomass status classes are created, by application of the WFD tresholds on Chl a as a proxy for phytoplankton biomass. The maps are made available in a portal, which allows to follow the lakes in time, zoom and download maps and time series.

EPSOSS takes advantage of the high investments made by the European countries and their international partners in ES data collection and dissemination systems (e.g. satellites, in-situ networks, ICT frameworks) and builds on top of those systems an added value application (geoportal) for the scientific community and the Black Sea relevant decision makers on environmental issues. ESPOSS offers: - Friendly interface - easy to use graphical user interface and intuitive workflows. - 10 000+ satellite derived data layers - the product portfolio includes: Sea surface temperature, chlorophyll concentration, diffuse attenuation coefficient, total suspended matter, etc. - Modern architecture - ESPOSS architecture design is driven by service-oriented architecture design principles, and use open standards from IETF, W3C, OASIS, ISO/TC 211, and OGC. - Open source based - ESPOSS GeoPortal is built completely with free and open source software. - Modular and scalable - the geoportal is based on a modular and scalable software architecture that enables an efficient deployment, control, and management of active services. - Network services - implements Open Geospatial Consortium (OGC) standards for data retrieval (WMS, WCS, WFS) and server-side processing (WPS). - Active community - fast growing international user community. - Powerful visualizations - effective data visualization methods, suitable for analysis of big volumes of multi-temporal data. - Server-side processing services - currently the service has interfaces for the following types of geospatial processing functions: buffer, clip, resample, profile and raster algebra.

A cost-effective method for accurate water depth mapping of the worlds shallow coastal areas based on high resolution satellite images. The method is globally applicable.
