| Sr.No. | Plane Surveying | Geodetic Surveying |
| 1 | The earth surface is considered as a plain surface | The earth surface is considered as a curved surface |
| 2 | The line formed by any two points are considered as a straight line – as the same angles are plain angles | The line formed by joining any two points are considered as arch –as the same angles are spherical angles |
| 3 | Plane Surveying Effect of the curvature of the earth's surface is ignored. | Geodetic Surveying Effect of the curvature of the earth's surface is included. |
| 4 | Length up to 12KM is treated as plane surveying. | Length more than 12KM is treated as geodetic surveying. |
| 5 | Plane Surveying Suitable for small area surveying | Geodetic Surveying Suitable for large area surveying |
| 6 | Plane Survey accuracy is low | Geodetic Survey accuracy is high |
| 7 | Involves smaller areas less than about 260 km2. | Involves larger areas more than about 260 km2. |
| 8 | Economical and easy survey method | The special instrument needed and long survey method |
| 9 | Knowledge of plane trigonometry is required. | Knowledge of spherical trigonometry is required. |
| 10 | Used in general civil engineering survey project work | They are used for the precise location of a widely distant area. |
| 11 | Plane surveying uses normal instruments like a chain, measuring tape, theodolite, etc. | Geodetic surveying uses more precise instruments and modern technology like GPS. |
| 12 | Done locally by the individual organization | Done by the concerned state or government department. |
