Geodetic Surveying | Trigonometrical SurveyingSunday, August 15, 2010 3:11
When the survey conducted by considering the earth’s surface spheroidal, or by considering the curvature of earth.Then this type of survey is known as Geodetic Surveying.
Since we consider earth to be spheroidal so the line joining any two points on the surface of the earth must be curve or is an arc of great circle.
It is also known as trigonometrical surveying. This type of survey is conducted where Large distances and areas are to be surveyed.
Characteristics of Geodetic Surveying :
Following are the characteristics of Geodetic Survey.
- Very refined instruments are used in this survey.
- High precision is achieved through this.
- Very refined methods of observation and adjustment are used.
