Kurzbeschreibung (Abstract)
Geographic Information Systems (GIS) are tools for acquiring, managing, analyzing and presenting in different ways spatially related information. Because the racy hardware development, especially the technical advances in automatic data acquirement, it becomes possible to acquire 3D geometrical data. There are many application areas where spatially related information is very useful, like archeology, telecommunication, environmental protection, and tourism. In the context of such a 3D-GIS in contrast of pure visualization systems, the analysis of the three-dimensional data plays a decisive role, in the special in connection with semantic information. An essential deficit of previous solutions is the absent support of typical functional demands on a 3D-GIS through the underlying onceptual data model. Such a data model must duplicate information on the 3D geometry and semantic of space-oriented objects, but also the topological relations of the objects among one another Goal of the work is the realization topological and space-oriented queries within a 3D-GIS. Thereby it will be mounted on an existing 3D-GIS. In the frame of this work, a 3D-Geo data server is supposed to be realized on basis of a databank system, that typical GIS functionality supports. In addition are an object-relational and an object-oriented databank system to compare. In single, following points are to be worked: - State of the art - Conception of a logical data model to the administration of 3D Geometries - Prototypical implementation of the data model and typical inquiries (Egenhofer-Operators, Region-Query) on the databases Oracle and Cloudscape - Critical comparison both solutions through analysis of data volume and performance of the inquiries
