Abstract
Demarcation of boundary marks for cadastral applications using the conventional surveying techniques (using EDM and total station) is that all points must be intervisible, that is, there must be a line-of -sight between surveyed points. This has restricted the efficiency of such technology. With the advancement of satellite technology, positioning with high accuracy can be achieved using the Global Positioning System (GPS) technology (Leick, 1995). The GPS technology is able to challenge this short range intervisibility constraint. The capability of this system towards point positioning is also highly recognized in mapping application. In this study, the capability of GPS receivers towards demarcation of points is explored. Discussion will be made on the technique of survey and the capability of the equipment used. Comparison will be made on the derived bearing and distance as compare to EDM traverse. The relationship of the coordinate system used in Malaysia as compare to GPS system will also be discussed.
