ABSTRACT
In Chapter 6 the possibilities of maintaining and analyzing 2D and 3D spatial objects in a geo-DBMS were described. A geo-DBMS is part of the new-generation GIS architecture, as seen in Section 5.6. For this research on 3D cadastre, 3D aspects of GIS other than geo-DBMS functionality are also important. The implementation of a 3D cadastre addresses the issues of inserting, maintaining, querying, editing, and visualizing 3D geo-objects in general. These are core topics of 3D GIS. Therefore, the state of the art of 3D GIS is described in Section 7.1.
