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 setting out of circular curve we details discuss offsets from long chord, offset from tangent, offset from chord produced in linear method & tape & theodolite/rankine method / tangential / deflection angles, two theodolite method, tachometer method in angular method.
Compass is a survey instrument used for the measurement of horizontal angles and the bearing of a line of sight.Surveyor Compass and Prismatic Compass are discussed in detailed.
