How to Use This Calculator
  1. Enter the number of traverse legs and the bearing and distance for each leg.
  2. Input the starting coordinates (Northing and Easting) and close back to the origin.
  3. Review the Raw Angular Closure Error and Adjusted Bearings after Bowditch correction.
  4. Check the Linear Closure Error and the Traverse Precision ratio.
  5. Use the Adjusted Coordinates output to compute final parcel areas and legal descriptions.

What each input means

Bearing Leg 1
Azimuth bearing from north for leg 1 (0-360 degrees).
Distance Leg 1
Measured horizontal distance for leg 1.
Bearing Leg 2
Azimuth bearing from north for leg 2.
Distance Leg 2
Measured horizontal distance for leg 2.
Bearing Leg 3
Azimuth bearing from north for leg 3.
Distance Leg 3
Measured horizontal distance for leg 3.
Bearing Leg 4
Azimuth bearing from north for leg 4.
Distance Leg 4
Measured horizontal distance for leg 4.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Bearing Leg 1 = 45, Distance Leg 1 = 500, Bearing Leg 2 = 135, Distance Leg 2 = 400 = 8 input(s) provided
  2. Calculate Linear Closure Error
    Linear Closure Error
    0 = 0
  3. Calculate Precision Ratio
    Precision Ratio
    Perfect closure = Perfect closure
  4. Calculate Latitude Misclose
    0 = 0
  5. Calculate Departure Misclose
    0 = 0
