a) a closed traverse survey involved measurements of angels (using theodolite) and distances between 3 stations A, B, C, from the data given in the table below, determine and correct the closing errors in angular measurements and in northing and easting (of the sides), and hence determine the corrected values of stations coordinates, where azimuth of AB 90° and coordinates of (A) are (500 N, 500 E). Finally, compute the traverse area from its coordinates. measured measured point side length angle A 60 12 10 АВ 110.5 60 31 44 ВС 111.7 59 16 15 СА 112.3 A

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.
