Difference Between Plane Surveying and Geodetic Surveying

We have discussed about plane surveying and geodetic surveying before in another articles.

  1. Plane Surveying
  2. Geodetic Surveying

Plane Surveying and Geodetic Surveying

Five major differences between plane surveying and geodetic surveying are given below.

Plane surveying

Geodetic surveying

  • Effect of the curvature of the earth surface is ignored.
  • The earth surface is assumed to be plane, i.e. two dimensional.
  • Involves smaller areas less than about 260 km2.
  • Lower degree of accuracy.
  • Done locally by the individual organization
  • Effect of the curvature of the earth surface is included.
  • The earth surface is assumed to be spherical, i.e. three dimensional.
  • Involves larger areas more than about 260 km2.
  • Higher degree of accuracy.
  • Done by the concerned state or government department.
