Example 15.7 Design of a Compound Curve Figure 15.23 illustrates a compound curve that is to be set out at a highway intersec- tion. If the point of compound curve (PCC) is located at station (565 + 10.5), deter- mine the deflection angles for setting out the curve. 60 340 PČC 26 PC 26 PT R,-150 m 34 R,-105 m Figure 15.23 Compound Curve for Example 15.7

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.
