  • This paper discusses 3D strata objects registration and implementation within the Land Administration Domain Model (LADM) framework in Malaysia. LADM - ISO 19152:2012 provides a conceptual description for a land administration system, including 3D strata objects registration. Standardization provides flexibility to the data model, making it easier for spatial data handling. The main concern of this research is the conceptual model which has yet to be implemented by the national authority. This research will discuss the practical pathway towards realizing LADM-based 3D strata objects registration in alignment with the jurisdictional settings in Malaysia. An accurate 3D cadastre for a property including strata has become important for the land administration system. Strata objects registration has the following aspects - parcel unit, accessory unit, common property unit, limited common property unit and land parcel. Presently, in Malaysia, all these objects’ representation is in 2D. This paper focusses on extending the representation of those strata objects to 3D. The prototype development begins with the data modelling i.e. selecting relevant object classes and extending the classes with attributes. It focuses on data conversion from an existing database i.e. strata.xml format to an open source database (i.e. PostgreSQL). The visualization and application modules will then be developed using an open source platform (i.e. QGIS). The developed prototype is able to answer all questions related to strata aspects which include ownership, share unit, Management Corporation (MC), spatial source document and strata objects. We anticipate that this work could serve as the model for other national authorities having similar land administration systems especially strata objects registration including the future Spatial Data Infrastructure (SDI) initiative in Malaysia.
