Types of Surveying

Division of Survey:-

      Geodetic Surveying
       Plane surveying

Geodetic or Trigonometrical Surveying:

           *When the radius of curvature of earth is taken in to account.
           *Large area and large distances are covered.
           *Object of geodetic survey is to determine precise positions on the surface of earth.
            *Refined Instruments and Methods are used.
             *Conducted by Government agencies.

Plane Surveying:

               *When radius of curvature of the earth is not taken into account.
               *Small area and small distances are covered
                *Degree of accuracy is  comparatively low.

Classification of Survey Based upon Nature of field:-

       *Land Survey
       *Marine Survey
       *Astronomical Survey

Based upon Object of Survey Geological Survey:-

        *Mine Survey (Mineral wealth such as coal, gold)
        *Military Survey(Points of strategic importance)

Based upon Method Employed:-

          *Triangulation
          *Traversing

Based upon Instrument Used:-

          *Surveying by Total Station
          *Chain Survey
          *Theodolite Survey
          *Compass Survey
          *Plane Tabling
          *Photographic and Aerial Surveys
