Survey accurate multipurpose cadastre in Malaysia

Abstract

MultiPurpose Cadastre (MPC) has a potential to support spatially enable government, private sectors, and society in general, and to expand computer support in the process of visualization, organization and management of useful land information. The Geographic Information System (GIS) applications of MPC database can be divided into four main sectors namely economic, social, environment and infrastructure. Therefore, MPC will serve as the most important geospatial dataset required for economic, social and infrastructure development for the country and hence will be one of the catalyst for gearing the nation towards high income economy by year 2020. In the endeavour to develop MPC for Malaysia, Department of Survey and Mapping Malaysia (DSMM) has embarked on a Pilot Project for the Federal Territory of Putrajaya. The main reference base-map is the survey accurate National Digital Cadastral Database (NDCDB). NDCDB contains all information obtained from cadastral survey jobs related to boundaries of land parcels. The existing NDCDB, which covers the entire country, has been referenced to the new Geocentric Datum for Malaysia 2000 (GDM2000).It has been adjusted with respect to cadastral control infrastructure developed using Global Positioning System (GPS) MyRTKnetto provide a homogenous and seamless cadastral network for the entire Peninsular Malaysia and the Federal Territory of Labuan. The targeted spatial accuracy of NDCDB is better than 5 cm in the urban area and 10 cm in the rural area. On the other hand, the main source of large-scale geographical features for urban areas will be based on the Mobile Terrestrial Laser Scanning (MLTS) surveythat is also referenced to GDM2000 and Mean Sea Level (MSL) height datum.However for rural areas,existing database from State Geospatial Data Centre (SGDC) at the scale 1:10,000 to 1:25,000 will be used. The survey accurate MPC database will include the following fundamental layers: i) NDCDB; ii)two-dimensional large scale geographical features; iii) three-dimensional city model; iv) utility data; andv) street addresses. MPC for Putrajayawill be developed based on On-Line Web Access or OWA and will be accessible to the government, private and public users. The pilot project towards the development of Survey Accurate MPC for Putrajaya will provide informative insight on thefuture directionin implementingnationwide MPC and new cadastral management in Malaysia.
