Transit Rule Adjustment
Balance a closed traverse by distributing latitude and departure misclosures according to their component magnitudes.
Transit Rule
Enter the observed traverse bearings and distances. The calculator derives latitude and departure, computes the linear misclosure, applies Transit Rule corrections proportional to the absolute observed components, and verifies the adjusted closure.
Starting Coordinate
Optional. If supplied, adjusted coordinates are calculated for every station.
Traverse Settings
Bearings are clockwise from North. Latitude = L cos θ; departure = L sin θ. North/East are positive.
Observed Traverse Lines
| Line | To point | Bearing | Distance | Remove |
|---|
For a closed traverse, use at least three lines and make the final line return to the starting station.
Transit Rule adjustment reference
The Transit Rule distributes latitude and departure misclosures separately in proportion to the absolute observed latitude and departure of each course. This makes the corrections depend on the component magnitudes rather than on line length.
