3D Modelling of Modern Urban Building Complexes and Sub-units Concept in 3D Cadastre

Abstract

As space is a fast-reducing commodity in cities, buildings are developed as multipurpose building complexes used for residential, commercial and others. 3D cadastre represents these building complexes as 3D objects with individual building units that have shared surfaces or adjacencies. However, building complexes are often modelled as a single volume. This paper presents the methods to model a 3D building complex with sub-units of mixed uses. A building complex composed of commercial and residential sub-units was modelled based on a building plan and visualized in GIS ready format. The 3D model consists of a set of volumetric units within an exterior shell of the building complex. The sub-units are displayed according to its uses. This can facilitate further spatial analysis that requires adjacency information of sub-units within a mixed-use building complex.

Marine Cadastre Data Models With Temporal Aspect – Review

“…spatial cadastral data, and created the geodetic-cadastral foundation for a legal framework for utilizing all available land space. For Morocco is the implementation of a 3D cadastre using integrated method based on BIM and 3D GIS, (Salleh et al 2022). The methodology shows the value of such integration for the effective administration of cadastral data (Sun et al, 2020).…”

“…Four basic types of rights have been identified and are: -'State rights, Public rights, Environmental RRR (rights, responsibilities, restrictions) and finally the Usage and Exploration rights' respectively. The State rights is on jurisdiction or control of affairs, Public rights on the hand is on constitutional rights of citizen and the unlimited access to the marine space without hindrance, Environmental(RRR), (Salleh et al,2022), refers to the protection and conservation of water resources, preserved areas and cultural heritage. (Fulton et al, 2015;Alberdi & Erba, 2020).…”
