Difference between Plane and Geodetic Surveying
| Plane Surveying | Geodetic Surveying |
| Curvature of the earth is not taken in to consideration | In this curvature of earth is considered. |
| In plane Surveying, line joining any two points of triangle formed by any three points is considered as straight line and plane triangle are assumed to be plane angles. | In geodetic surveying line joining two points of triangle formed by three points is considered as curved line of spherical triangle and angles of triangle are considered as spherical angles. |
| This survey is done on smaller area less than 250km2 | This survey is done on large area greater than 250 km2 |
| Required accuracy is competitively low. | High accuracy is required |
| Simple methods and instruments can be used as the required accuracy is low. | Very refined methods and instruments are used. |
