Traverse Survey
Traverse Survey, Types of Traverse- Closed Traverse, Open Traverse. Method of Traversing– Linear Measurement, Angular Measurements: Loose Needle Method, Fast Needle Method, Method of Included Angle, Method of Direct Angles, Method of Deflection Angles. Balancing the Angle of Traverse- Average Correction Method. Latitude And Departure- Latitude (L), Departure (D). Checks in a Closed Traverse- Loop Traverse, Link Traverse. Closing Error, Relative Error of Closure or Relative Precision, Method to Correct Clothing Error- Bowditch’s Rule, Transit Rule.
Topics
In this triangulation chapter, we detailed discuss about classification of triangulation, triangulation layout, well condition triangle, trilateration, system of framework, objective of triangulation, ETC.
In theory of errors we details discuss theory of errors, occurrence of error, type of error, gross errors or mistakes, systematic or cumulative errors, accidental or random errors, precision, accuracy, true value, true error, most probable value (M.P.V), principle of least square, residual error, law’s of weights, probable error, error in computed result.
