Compound Curve Consists of two or more consecutive simple curve having different radius, but whose center lie on the same side of the curves, likewise any two consecutive curves must have a common tangent at their meeting point. When two such curves lie upon opposite sides of the common tangent, two curves then turns a reversed curve. In compound curve, the point where the two curves join is called the point of compound curvature (PCC). PI TR TL PCC 2 T1 T2 PT PC 12 R2 R1 02 01

Instruments for Surveying

Surveying is the practice that determines the relative three-dimensional positions of many different points on the earth’s surface. There are various instruments used in Surveying like Theodolites, Total station, Tripod stands, Plane table, etc. for measuring horizontal angle, vertical and sloping angle, which are very useful for giving accurate and precise measurement.
