This paper investigates several aspects of the Land Administration Domain Model (LADM, ISO 2012) associated to 2D and 3D cadastral situations within Malaysian cadastral registration system. Literature review shows that many countries propose their own profile based on the LADM such as The Netherlands, Portugal, Indonesia, Korea, Japan, Australia/ Queensland, Cyprus and others. Malaysia is one of the potential candidates towards LADMbased country profile, as proposed in this paper. Several aspects of the LADM such as the RRR’s (Rights, Restrictions and Responsibilities), the ’Spatial Unit’ and ’Party’ will be described related to 2D and 3D cadastral situations within the UML modelling language as a tool for the data modelling. Code lists are used to describe a more open and flexible enumeration values and associated to Malaysian mapping standard. Code lists are useful for expressing a long, and potentially extensible, list of potential values. The code lists included in the LADM aim to allow the use of local, regional or national terminology. We plan to utilise cadastral datasets from Malaysian NMA (National Mapping Authority, ’JUPEM’) and Land Office agency to illustrate the various cases. Note that the spatial data comes from JUPEM, and registration (non-spatial data) from the Land Office. In this paper the modelling of Rights, Restrictions and Responsibilities (RRR) will be discussed with a focus on the modelling of holding shares in a RRR (Lemmen et al. 2010). A share in a right has a constraint that the sum of all shares should be equal to one. In principle, all rights, restrictions and responsibilities are based on an administrative source. A ‘SpatialUnit’ is a point (or, multi-point), a line (or, multi-line), representing a single area (or, multiple areas) of land (or water) or, more specifically, a single volume of space (or, multiple volumes of space). The individual points are associated to ‘SpatialSource’ class. 2D and 3D representations of spatial units use boundary ’face strings’ and boundary ’faces’. Parties are natural persons, or group of persons, or juridical persons, that compose an identifiable single (legal) entity. A juridical person may be a company, a municipality, the state or a farmer cooperation. Database construction for spatial and non spatial data will be carried out using Oracle Spatial. The database schema is based on the LADM conceptual model with a country profile for the Malaysian cadastral registration system. Data from the Oracle database can be accessed by Bentley MicroStation software for 2D and 3D visualisation and editing. The Structured Query Language (SQL) will be used to query and extract the data from the database.
