INTEGRATING QUALITY MANAGEMENT INTO A 3D GEOSPATIAL SERVER

Abstract. In recent years the technology and workflow for producing and management of large 3D urban models has been established and widely been used. Standards such as CityGML enable the modelling and exchange of semantically enriched multi-purpose 3D urban models for applications like urban planning, public participation, environmental simulation and navigation. However, data quality management is essential to control and enhance the quality of these models in order to be able to meet the needs of the aforementioned applications. Quality management should be performed throughout the whole lifecycle of geospatial datasets – from data acquisition to processing, analysis and visualisation. In this paper, we therefore focus on the integration of a quality management software module into a 3D geospatial data server. First results of a prototype system developed at HFT Stuttgart together with Fraunhofer IGD will be presented in this paper as a starting point for further research into the field of quality management of 3D city models.
