Developing 3D Registration System for 3D Cadastre

Abstract

The establishment of Malaysia cadastral system is to monitor matters of land especially the land ownership. The system is setup to ensure consistency in cadastral information that comes from cadastral survey and cadastral land registration. In general, the cadastral survey and cadastral land registration are managed by Department of Survey and Mapping Malaysia (DSMM) and Land Offices (LO) respectively. The system for land registration is known as Cadastral Data Management System (CDMS) which is controlled by DSMM where as Computerized Land Registration System (CLRS) administered by the Land Office. A cadastre is normally a parcel-based and up-to-date land information system containing a record of interests on land (e.g. rights, restrictions and responsibilities). Currently, the system is based on 2D space. The cadastral object can be either a complete land parcel, parcel of storey houses (strata) e.g. apartments, flats residential or parcel below the surface (stratum). Demands from land owners as well as property owners show that it is insufficient to register cadastral parcel based on 2 D space. Real-estate property is actually in 3D. Current 3D GIS technology could be used to develop a registration system for 3D Cadastre and eventually a solution for complex 3D Cadastre objects or situations. Therefore, the new cadastral system should reflect the existence of the real-world objects - 3D physical objects and have its own legal rights. 3D technologies make it possible to establish 3D cadastre. This paper discusses a development of 3D registration system for cadastre objects in 3D. The main objective is to look into possibility of enhancing the current systems practiced by the DSMM and LO towards 3D cadastre registration. In other words, this research attempts to address one of the aspects in 3D Cadastre, i.e. how to register 3D objects and properties for 3D cadastre.
