  2. Integration of EO- / GeoData • Data integration is a key issue in environmental monitoring systems • With the availability of high quality GIS-data we are able to use it for a fine tuning of the algorithms in our thematic processors • The solution proposed is based on an integrated analysis of multitemporal multisensor data (IKONOS multispectral- and ERS-SAR data from tandem acquisitions) • After pre-processing each set separately (NDVI, average intensity, coherence) a pixel-based classification of the sealing information was done for each thematic layer (winter / late spring acquisitions) • The classification process was done based on masked regions defined by the ATKIS object classes (e.g. settlement, forests, agricultural areas) • Sealed areas were finally detected on a pixel based map overlay process including the pre-processed data

  3. Results: Sealed Area Mapping IKONOS – Multispectral Interferometric Signatures ATKIS – High level objects Map Overlay Algorithm • Due to the medium resolution but also due to double bounce scattering and corner reflections ERS-SAR with low potential in detailed urban mapping of sealed areas • Backscatter and coherence information with a higher sensitivity in rural regions
