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

Plane Surveying and Geodetic Surveying
Five major differences between plane surveying and geodetic surveying are given below.
- 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.
