Topography survey stages includes GPS control for installation and measurement of Bench Mark (BM), Main Polygon and slag points to determine height points and detail area measurement. The data was measured with interval of 10 meters. In each measurement it is required to acquire horizontal and vertical coordinate points in order to get 1:1000 and one meter contour interval for topography map. North to South survey lines at interval of 30 meters also need to be created and 5-10 meter points for collecting spot height and detail measurement. This is done using accurate survey equipment, Total Station.
Topography survey is intended to determinate the efficient CUT and FILL locations. Topographic survey is resulting AutoCAD drawing that is used for engineering grid elevation such as mill site design, water catchments area, water gates housing locations and access roads. The data will be provided in Lat/Long coordinates, other projections is upon request.
