A simple curve with a bearing of N 70° E on the back tangent and S 82°30' E on the forward tangent. The angle of the curve is 4.5 degrees. 10+345.43 is the stationing at the PC. It is proposed that the central angle be reduced by modifying the forward tangent's direction by 7°, while keeping the position of PT of the front tangent and the direction of the back tangent unchanged. is the new radius of the curve.

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.
