This paper discusses the design and development of a Malaysian geographical information system (GIS) database server for location data sources available in Malaysia, such as the Global Positioning System (GPS), WGS84, geocentric datum for Malaysia (GDM2000), geodetic reference system 1980 (GRS80), local geodetic measurements such as Malayan revised triangulation 1948 (MRT48 or KERTAU 48), Borneo triangulation 1948 (TIMBALAI 1948), Malayan Revised Triangulation 1968(MRT68), Borneo triangulation 1968 (BT68), local cadastral information such as the ECadastre coordinated cadastral system (CCS) developed by JUPEM and cellular coordinate information based on cell-based ID, E-OTD etc It describes the pros and cons of the above mentioned systems, analyze the accuracies and tolerance of the data source. It also highlights the disparities between different systems, and proposes fast methods to correlate and transform these data into a unified, reliable data source. Lastly it will cover the storage and retrieval process for the textual and graphical GIS data.
