Abstract

Abstract Global Positioning System (GPS) has been used to establish national geodetic control networks, to measure inter-plate tectonic movement, for mapping and GIS data collection, for construction site setting out and for cadastral boundary demarcation. In this study GPS handheld navigator is used to produce a cartographic map for relatively a big area by using GPS point positioning method in order to reduce efforts, time and cost. The obtained accuracy from using GPS personal navigator is in order of 3-5m. GPS point positioning method provides an excellent way for producing cartographic maps of scale 1:25000 or smaller. Moreover, in urban area intermingled with buildings, over 95% of the observations on cadastral property boundary and corners surveyed have good correspondences with the results obtained by total station technique.
