ABSTRACT
ABSTRACT: The “prosumer”—oriented GeoWeb2.0 approach of collaborative data generation where the distinction of producers and consumers of information blurs produced a new data source for urban geographic information: OpenStreetMap. This can be used in developing web-based and mobile Location-based Services such as POI-Search (spatial Yellow Pages), Routing and Maps in 2D. The Open Geospatial Consortium (OGC) has defined standards for those. On the other hand urban data management deals more and more with 3D city data. Also for that OGC has released standards such as CityGML-but in addition to that exchange format a web service for visualizing 3D city models is needed and available as a discussion paper-the Web 3D Service (W3DS). In this paper we show how these three-open user generated geodata, OpenGIS services for LBS and 3D urban models can come together in a Web Service based application to deliver rich urban 3D models and innovative applications by combining those heterogeneous sources of information in a new, but interoperable way.
