Investigation of data models and related requirements affecting the implementation of a multipurpose cadastre system in Malaysia

[摘要] One aim of this study was to investigate the state of development of multipurpose cadastre systems (MPCs) internationally, and, based on the findings to design a multipurpose cadastre data model enhancing the current cadastre system in Malaysia. A second aim was to determine the organizational and legal requirements for implementing a multipurpose cadastre system, within the current Malaysian context. As a final aim, the service oriented architecture (SOA) concept was examined to investigate how it might support the storage, maintenance and delivery of the different layers of data found in an MPC. The data model and service oriented architecture were developed using Oracle Spatial technologies and the SQL language. Sample data from the national digital cadastre database, utility data and topographic mapping data from Malaysia were used in the case study. The investigation enabled data from various agencies to be integrated into a single multipurpose cadastre database in the Oracle Spatial database environment, and a case study of an easement as a legal land object was executed. It was discovered that it was beneficial to show the complete legal situation of a parcel compared to the previous system where the user had to manually search for legal documents and deal with the ambiguous locations of legal land objects. The results of the SOA investigation showed that the application of the SOA concept to the construction of an MPC database will require extensive IT investment, especially a high specification server, but it is expected to reduce redundancy in data collection and processing and reduce the costs. The study also showed that existing legislation in the National Land Code 1965 should be amended. The principal conclusion is that an open source system should be adopted before any further investment in IT software and hardware is made. Another conclusion is that a multipurpose cadastre system has to be managed by personnel highly trained in spatial, programming and IT competencies. An open source system combined with the SOA concept seems the best option if a multipurpose cadastre system is to contribute to the sustainable management of land resources within a rapidly developing Malaysia.
