Correction In Latitude By Bowditch Rule Is Given By

By Aina Parasher|Updated : July 4th, 2022

Correction in latitude by Bowditch rule is given by-

  1. Total error in latitude x length of that side/perimeter of traverse
  2. Total error in latitude x perimeter of traverse/length of that side
  3. Total error in latitude/perimeter of traverse
  4. None of these

Answer: A. Total error in latitude x length of that side/perimeter of traverse

Correction in latitude by Bowditch rule is given by total error in latitude x length of that side/perimeter of traverse

Solution

Arbitrary Method: Surveyors alter measurements based on their collective experience.

Bowditch Method: It is adopted when both the linear and angular measurements are taken with extremely high accuracy. The Bowditch rule states that error in angular measurement is inversely proportional to square root of line length and error in linear measurement is directly proportional to square root of line length.

Correction= total error in latitude/departure×length of that side/perimeter of traverse

Correction in latitude by Bowditch rule is given by total error in latitude x length of that side/perimeter of traverse.

Graphical Method: Its foundation is the Bowditch rule. It is typically employed in compass traversing.

Transit Method: It is used when an angular measurement is more exact than traversing measurement. Only linear measurements were impacted by this strategy.

Axis Method: Only length is corrected using this method. It is used when the angular measurement is more accurate.
