Topography survey stages include GPS control for installation and measurement of Bench Mark (BM), Main Polygon and slag points to determine height points and detailed area measurements. Data is measured in 10-meter intervals. In each measurement, the horizontal and vertical coordinate points will be obtained to get a 1:1000 and one-meter contour interval. North to South survey lines at an interval of 30 meters also need to be created and 5-10 meter points for collecting spot height and detailed measurements. This is done by using accurate survey equipment, Total Station.

Topography surveys are used to determinate efficient CUT and FILL locations. Topographic surveys result in AutoCAD drawing that is used for engineering grid elevation, such as mill site design, water catchments area, water gate housing locations and road access. The data will be provided in Lat / Long coordinates; other projections are available upon request.
