Difference between Plane Surveying and Geodetic Surveying
Primary divisions of surveying are:
- Plane Surveying
- Geodetic Surveying
| Plane Surveying | Geodetic Surveying |
| The surveying in which earth surface is considered as plane surface. | The surveying in which curvature/surface of the the earth is considered as curved surface. |
| Earth’s curvature is ignored. | Earth’s curvature is considered. |
| The line joining any two points will be considered as straight line. | The line joining any two points/stations will be considered as curved line. |
| The triangle formed by any three points will be considered as plane triangle. | The triangle formed by any three points will be considered as spherical triangle. |
| The angles of triangle are considered to be plane angles. | The angles of triangle are considered to be spherical. |
| Plane Surveying is carried out for area less than 250km^2. | Geodetic Surveying is carried out for area more than 250km^2. |
| Surveying is carried out for small area. | Surveying is carried out for larger area. |
