Cost Optimized Trends in Contouring Using Hand-Held GPS
In this paper, the authors reveal the use of hand-held Global Positioning System (GPS) for the purpose of contouring. In this paper, 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 benchmark. 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.
