What is Geodetic Survey Very Short Answer :     A land survey with aquaracy  made to account for the curvature of the earth surface.                                 fig no 14.0 Instrument use in geodetic survey..................................................... Main instrument for  Geodetic Surveying   : Theodolite: It is the basic  surveying  unit used for  Geodetic Surveying  . Theodolite consists of a telescope which is placed on a swivel and it can be rotated both horizontally and vertically. Triangulation point are determined by the theodolite in  Geodetic Surveying  . Two circles-one vertical and another horizontal, are used to read out the readings. But in the modern theodolite the reading is done electronically.  Geodetic Surveying  can be done by geographers, engineers and surveyors specialised in related disciplines. Use of Geodetic Surveying  : Engineering purposes: The engineers uses  Geodetic Surveying  for finding out the exact loca

Check for reading level: submission b.s subtract from submission f.s b.s is bake side f.s is fore side is equal to last reading subtract first reading for example submission b.s is 3.14 submission f.s is 2.0 3.14-2.0=1.14 and last reading is 120 first reading is 100 so 120-100=20 1.14=20 result your reading is wrong when R.H.S=L.H.S your reading is aqurate
