This should include the processes of the analysis and improvement of heterogeneous spatial data structures. This paper describes the concept, architecture and functionality of such a system: the spatial Data Fusion System (DAFU). DAFU allows efficient use of heterogneous spatial information and creates the possibility to individual use of geo-data. \itemrv{~} \itemcc{} \itemut{data fusion; data integration; vector data; homogenization; heterogeneous geospatial data; data conflation} \itemli{doi:10.1007/978-3-642-31075-1\_33} \end
