This paper discusses 3D objects registration and modelling for cadastral objects within the Land Administration Domain Model (LADM) framework. A conceptual model as well as the associated technical model for the 2D and 3D objects have been proposed and developed for Malaysia. For both private and public land, the main subdivision of land in Malaysia is based on lots. In many continental European countries, ‘lot’ would be called ‘parcel’, but ‘parcel’ has other meaning in Malaysian context. The lots can have 2D or 3D representations. The Strata Title Act and Strata Management Act are very important for a large part of the Land Administration in Malaysia, and this is especially true for many 3D related situations. The Malaysian LADM country profile includes the support for these strata objects: building and building parts (all in 3D within a single lot), land parcel (with house no more than 4 storeys within a single lot), which can be refined with parcel unit, accessory unit, and (limited) common property unit including support for provisional and multilayer/underground aspects. In addition, the Malaysian country profile also supports the legal spaces for utilities. By developing a Malaysian country profile based on the international standard ISO 19152, the possible confusion related to terminology (e.g lots, parcels, strata, 2D, 3D) has been resolved. This is not only important for Malaysia, but also useful for many other countries, that have the strata title system.
