The amount of geospatial data continues to proliferate with recent advancements in information technology. Available geospatial data sources include mapping services (GoogleMaps,YahooMaps, etc.), Web2.0 based collaborative projects (OpenStreetMaps and WikiMapia), traditional geospatial data sources (raster maps, KML vector layers, etc.) and non-traditional geospatial data sources (phonebooks and property-records). To fully exploit these diverse geospatial data sources, we are developing an integrated approach to extraction and fusion of these sources within a unified framework.
To provide a common platform for such data integration and geospatial reasoning tasks, we have developed an integration framework that allows the user to interactively fuse different kinds of geospatial data sources and exploit the integrated data to carry out various geospatial reasoning processes.
