The following consecutive staff readings were taken with level and 5m staff at 70 m interval. The level has been changed after third, sixth and tenth readings, the elevation of first point and last point are (80 m and 84.96m) respectively. Readings are as follows: Bs BS 65 (1.25, 2.18, 2.05, 3.12, 1.57, 1.82, 1.47, 1.15, 1.95, 2.08, 2.08, 4.22, 3.1, 3.5, -3) 1- Find elevation of all points by the height of instrument method and apply appropriate check.

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.
