10. A line measured with a 30-m steel tape was recorded as 325.70 m. If the tape is found to be 30.05 m long during standardization, the correct length of the line is a. 325.16 m b. 325.70 m c. 327.45 m d. 325.44 m e. 326.24 m 11. A rectangular building 250.0 m (L) x 130.0 m (W) is to be laid out with a 30-m long steel tape. If during standardization the tape is found to be 30.03 m, the correct length and width to be laid out should be a. 249.75 x 129.87 m b. 250.25 x 130.13 m c. 249.87 x 129.75 m d. 250.00 x 130.00 m e. 249.97 x 129.97 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.
