A tilting level is used to run a set of precise levels to a construction project from benchmark DAM, whose elevation is 101.865 m. The line is run along a road that goes up a steep incline. To expedite the job, backsight distances are kept to 50  1 m and foresight distances are 20  1 m. The total length of differential levels is 4410 m. The elevation difference observed is 13.634 m. What is the corrected project elevation if the instrument has a sight line that declines at the rate of 0.3 mm per 50 m?

Coordinate Geometry of Survey

Coordinate geometry (COGO) is a method of inserting surveying or engineering data into geographic information system (GIS), computer-aided design (CAD), or mapping software. These data can be collected on the proposed construction site using standard surveying techniques and instrumentation or may be taken from existing maps, engineering plans, drawings, or records. Data gathered on the site includes coordinates of points, bearings, and distances between points. The data are noticed and noted through conventional surveying procedures, like a traverse or layout measurement series and it can be either digital or non-digital. The maps and plans are inclusive of boundaries, divisions, and other components, and these features are shown with coordinate values, the lengths, offset distance, and bearings between them.
