The top of the mast signal 1750m away was sighted through a transit with recorded vertical angle of 4° 55'. The height of the mast is 5.5m and the height of the instrument above the point where it was set up is 1.15m. the elevation of the base of the signal 'B' is 167.23m, compute the elevation of the point under the transit 'A' with allowance due for curvature and refraction using h= 0.067k

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.
