The survey is done mainly to make maps and plans for construction projects. The principle of compass surveying is traversing, which involves a series of connected lines. #BlubIn compass traversing the directions of survey lines are fixed by angularmeasurements and not by forming a network of triangles. Principle of Traversing deflection angle 3 d23 dS1 1 d12 traverse point S 2 traverse legs • Determine the WCB of the first leg; • measure the length of the first leg; • compute the coordinates of the traverse point No. These elements form the basis for collecting data, measuring distances, and determining directions in a traverse survey. pwj bsmrvhy qyazitqo mong gzgkoc wnfvi ndby jsq twudvpv tppeww
