TRAVERSE - Coggle Diagram

- - - - Total required angle = (Final forward bearing - Initial back bearing) + (m * 180 degree)
      - *where :
        
        m is an integer, in most cases, m will be (n-1) or n or (n+1)
        
        n is the no. of left-hand angles observed
        
        note : value of m is obtained by assuming that observations are gross-error free
    - - Calculate :
        
        Latitude and departure
        
        Linear misclosure and adjustment of latitude and departure
        
        Forward bearing
        
        Coordinates of certain stations
        
        Angular misclosure and Angular correction
        
        Initial back bearing and final forward bearing
    - - Latitude/departure calculation (Linear misclosure 1:10,000)
      - Latitude/departure correction (Linear misclosure 1:10,000)
      - Latitude/departure adjustment (Linear misclosure 1:10,000)
      - Coordinate calculation
- - - - The observe angles can be internal/external angles
      - AM are found by comparing the sum of the observed angles with one of the following theoretical values :
        
        Internal angles required = (2n - 4) * 90 degree
        
        External angles required = (2n + 4) * 90 degree
        
        *where n is the no. of angles measured
    - - Latitude/departure correction
      - Latitude/departure adjustment
      - Latitude/departure calculation
      - Coordinate calculation
      - Area calculation (coordinate method)
