LADM Implementation Prototype for 3D Cadastre Information System of Multi-Level Apartment in Indonesia

SUMMARY Limitations of land supply for infrastructure developments in urban areas led to the development of multi-level and vertical buildings. Massive developments and uses of high rise buildings and constructions such as muti-level apartments and overpass structures in big cities in Indonesia indicated that the demand for space above the ground surface is rapidly increasing in recent years. Regardless the existence of policy and standards of services on land and property registrations, the trend will potentially cause ineffective space management as there is no dedicated information system to efficiently and effectively register and manage information related to boundary of property objects and spaces above the ground and their corresponding rights of ownerships and uses. This paper is dealt with a development of an information system prototype that deals with the registration and management of objects and spaces related to cadastre system (3D cadastre) . Currently the registration system does not store geometry and attributes of ownerships of spaces of property objects in a single system whereas there is a potential opportunity to adopt Land Administration Domain Model (LADM) basic classes in enhancing registration and visualization of land and property spaces. For that reason, a prototype was built based on a simple implementation of LADM basic classes by conforming to the national law on strata title for multi-level appartment and regulation of national land office related to land registration systems. This research uses 3D spatial data stored in CAD format of commercial units in multi-level building in city of Semarang. Enterprise Architect UML CASE Tools 9.3 is used to create a spatial database schema concerning the implementation of LADM basic classes suited to strata title
