Building licensing requires that different types of spatial data be integrated into a single model without losing semantic information. During the checking process it may not be possible to compare and check all data parameters directly. Therefore, models must be evaluated and semantically and geometrically transformed when necessary. This paper introduces a potential workflow concept for building licensing. An approach on how to use data from different models and how to transform data for parameter checking is presented, and a brief outlook is given. 1. INTRODUCTION With the introduction of E-Govemment processes, an increasing number of services provided by public administration will use the support of Internet technology. Due to the EU Services Di rective (EU 2006) this trend will even increase within upcoming years. Urban land-use planning and building licensing are two sectors of public administration in which Internet based proce dures are rarely used. This is mainly due to the many different legal provisions on federal, state and municipal levels. Addi tionally, the data involved are very complex and heterogeneous. Most of these data have a spatial context and can be provided via standardized interfaces. Among these are: • 3D Building Information Models (BIM) in IFC (IFC 2008) or DXF CAD data representing a planned building; • virtual 3D City Models based on OGC® (Open Geospatial Consortium) CityGML for the existing buildings surround ing the planned construction or the relief of the construction site (Groger, G., et. al., 2008); • semantic data models for preparatory or legally binding land-use plans in the XPlanGML format (Benner, J., et. al., 2008). This paper outlines the concept for a software system that inte grates these types of geo information with additional, non geometric information of the building project. The main func tion of this software will be to automatically check a “digital” building application for its consistency with legal regulations. A geometric/semantic data model of the planned construction as well as a formalization of the relevant legal regulations is re quired for the automatic checking of building applications. With XPlanGML, a semantic data model exists for urban planning documents, which is based on German federal planning law (Baugesetzbuch (BauGB), Baunutzungsverordnung (Bau-VO)). An appropriate formalization does not yet exist for other build ing laws and building bylaws. Therefore, the first stage of the project will concentrate on checking building applications against the regulations of a XPlanGML-based, legally binding land-use plan. 2. RELATED DATA MODELS 2.1 Industry Foundation Classes (IFC) The Industry Foundation Classes (IFC, ISO/PAS 16739), de veloped by the international alliance buildingSMART, are an open standard for building models representing different do mains like architecture, building services and facility manage ment. The model is intended to support the complete life cycle of the building (buildingSMART 2008). The IFC model consists of objects, properties and relations. The building structure is hierarchically subdivided into spatial ele ments like projects, sites, buildings and building storeys. All building elements like walls, slabs and roofs, are contained within the spatial elements. Spatial elements do not usually have a geometry (Eastman, C.M., 1999). Figure 1 shows an example of a complete IFC model with 4 storeys, 21 spaces and the corresponding building elements. Figure 1.
