Different methods of contouring are:
Tachometric method of contouring
- This method is used for angular surveying.
- This method is best suited for hilly terrains as the number of stations which can be commanded by a tachometer is far more than those by a level and thus the number of instrument settings is considerably reduced.
Direct Method
- The reduced level of different selected points is located and joined to form a contour.
- This method is accurate but very tedious and slow.
Square method or grid method
- In this method, we draw a grid point on the ground and measure the reduce level of all these points.
- It is generally used in plain terrain.
Cross Section method
- This method is generally used for hilly terrain to produce contour lines.
