Using the Google Earth Pro application, a BSGE student measured the dimensions of the main academic area of Caraga State University, Ampayon, Butuan City Campus as follows with their respective standard deviations: Side Observed value (m.) Standard Deviation st 401.97 * 0.76 s2 400.43 * 0.78 + 0.76 + 0.78 $3 401.97 主 $4 400.43 What is the area of the academic area and its standard deviation?

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.
