SummaryThe basic idea of the project is to build on the technological achievements of precursor national projects, notably OFEW and DeMarine, during which technologies have been developed and tested for the German Wadden Sea, and to further develop and adapt these technologies to the requirements of other intertidal areas. Different intertidal flats are subject to different bio-geo-physical conditions and the monitoring requirements differ according to national implementations of European directives. We will therefore (i) further develop the classification beyond the current state and adapt it to other areas than the German Wadden Sea and (ii) validate the classification maps and assess their quality by the users. The Portuguese Tagus estuary has been chosen as demonstration test site. Different remote sensing data of the region will be used, along with in-situ data used for the calibration of the algorithms and for its validation. The method to be applied to the Tagus Estuary combines the spectral information from optical remote sensing data with information gained from SAR signatures at X- and L-band. During the past months TerraSAR-X data have proved to be invaluable for the identification of different surface types on intertidal flats. This information has entered into the existing classification scheme. The final deliverables will be a classification of intertidal flats of the Tagus Estuary derived from the different data sources. Maps will be produced to demonstrate the potential of remote sensing applications to the end-users. The investigations proposed here are funded by the European Space Agency (ESA).
