Q: The survey in which the curvature of the earth is taken into account is called:
  • A. Plane survey
  • B. Topographical survey
  • C. Geographical survey
  • D. Geodetic survey
Correct Answer: Option D - Geodetic surveying– It is that type of surveying in which the shape of the earth is taken into account. All lines lying in the surface are curved lines and the triangles are spherical triangles. • It, therefore, involves spherical trigonometry. • All geodetic surveys include work of larger magnitude and high degree of precision. • The object of geodetic survey is to determine the precise position on the surface of the earth, of a system of widely distant points which from control stations to which surveys of less precision may be referred.
