【 摘 要 】

This paper presents the generation of the 3D national geo-data model of Turkey, which is compatible with theinternational OGC CityGML Encoding Standard. We prepare an ADE named CityGML-TRKBIS that isproduced by extending existing thematic modules of CityGML according to TRKBIS needs. All thematic datagroups in TRKBIS geo-data model have been remodeled in order to generate the national large scale 3D geodatamodel for Turkey. Within the concept of reference model-driven framework for modelling CityGMLADEs in UML, the first step is conceptual mapping between CityGML and national information model. To testall stages of the framework for Urban GIS Turkey, Building data theme is mapped with CityGML-Buildingthematic model. All classes, attributes, code lists and code list values of the TRKBIS is tried to be mapped withrelated CityGML concept. New classes, attributes and code list values that will be added to CityGML Buildingmodel are determined based on this conceptual mapping. Finally the new model for CityGML-TRKBIS.BI isestablished in UML with subclassing of the related CityGML classes. This study provides new insights into 3Dapplications in Turkey. The generated 3D geo-data model for building thematic class will be used as a commonexchange format that meets 2D, 2.5D and 3D implementation needs at national level.
