Technological aspects of a full 3D cadastral registration

In this paper, we present a new conceptual model for a full 3D cadastral registration system. Two important components are: (1) the 'surface parcel partition' based on a detailed elevation model and (2) the volume parcel and its representation. Technological solutions for both parts are not yet available in commercial Geo-ICT software, and therefore solutions have been investigated, designed and developed (in a Geo-DBMS environment). A number of countries in the world do already have legislation allowing the registration of volume parcels, sometimes even including detailed regulations for 3D survey plans. However, until now, these have not yet been integrated in the cadastral information system. A 3D case from Queensland, Australia is presented, and a prototype is realized based on an integrated 3D cadastral information system: elevation-model-based surface parcels complemented with volume parcels.
