transit rule. A rule for adjusting the closure error in a traverse. The transit rule distributes the closure error by changing the northings and eastings of each traverse point in proportion to the northing and easting differences in each course.

What is transit method in surveying?

Transit Method. This method is developed for balancing a traverse in which angles are measured with a higher degree of precision than the lengths of the sides. It is based on the assumption that the error in departure (or latitude) of a traverse side is proportional to its departure (or latitude).

What is meant by balancing traverse?

 A traverse is balanced by applying corrections to latitudes and departures. This is called balancing a traverse . In case of a closed traverse, the algebraic sum of latitudes and departures must be equal to zero (i.e. L=0 and D=0).
