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