Integrating Cadastral GIS Database into GPS Navigation System for Locating Land Parcel Location in cadastral surveying

Cadastral surveys deal with one of the oldest and most fundamental facets of human society, which is ownership of land. They are the surveys that create, mark, define, retrace, or reestablish the boundaries and subdivisions of the public lands in Malaysia. Knowing exactly where the boundary lines are is important for many different activities. If there any consideration of constructing a building on the property, conducting a cadastral survey is a requirement to avoid any possibility of encroaching into a neighboring land. This type of survey can ensure that fences and other improvements are located in exactly the right position within the boundary. Originally used to ensure reliable land valuation and taxation, today these surveys are mainly used to solve boundary disputes. The boundary mark is important in starting a Cadastral survey job. This is because the coordinate as well as bearing and distance is a necessity to start the survey job in determining all the boundary of a new or existing parcel. One of the common issues in starting a new cadastral survey job is finding the location of the work site or lot parcel. It may take a long time to refer on the certified plan and locate the site manually. The surveyor may take time to go and find the location of the work site only by referring the certified plan especially in the area that not really familiarize with it. They may take a few days in locating the area. They also need to find the land owner to conform the location of the lot parcel. Therefore, using this new portable GPS that has been integrated with cadastral GIS database, it can help surveyor to save their time to reach at lot parcel. This automatically saves their time in locating the boundary mark. It helped surveyor when the lot parcel now can also be navigated in this portable GPS. Therefore, in this paper will study on the integration of land parcel data in the Malaysian Cadastral database (PDUK) into GPS system to assist surveyor in locating parcel location based lot number of the land.
