Abstract: This paper reveals the use of hand – held Global Positioning System for the purpose of contouring. In this research, major stress is laid on the use of cheaper and accurate GPS along with the conventional instruments. A hand – held GPS is used to determine the position of the particular station and the corresponding reduced level of the occupied station is determined with respect to a Temporary Bench Mark. The data collected is interpolated using Surfer 8.0 software. The profile of the surface generated was found to be in accordance with the actual topography of the site. The accuracy of the hand – held GPS is also taken into account from the data collected from some of the researches undertaken by various organizations. Thus, the use of hand – held GPS along with the cheaper conventional leveling instruments for the purpose of contouring prove to be very cost effective and considerably accurate.
