CityGML defines geometry and topology for city modeling, also focusing on semantic aspects of 3D city information. Within this context, CityGML was developed as an international standard of the Open Geospatial Consortium (OGC) for 3D city modelsвЂ™ representation and exchange. Nevertheless, these opportunities cannot be totally exploited because of deficiencies in standardization and interoperability in these systems. The existing geographic information systems and the different methods of three-dimensional modeling allow for better management, visualization and dissemination of information. Despite the progress in the field of geographic information systems and 3D modeling techniques, there is no fully digital 3D cadastre. The complexity of urban environments and the strong need for land administration, intensify the need of using a three-dimensional cadastral system. In recent years the development of technology and the lifting of several technical limitations, has brought the third dimension to the fore.
