Which method of contouring is most suitable for hilly terrains? Correct Answer Tachometric method

Explanation:

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.
