Q1:

If arithmetic sum of latitudes of a closed traverse is ∑Lat and closing error in latitude is dx, the correction for a side whose latitude is l, as given by Transit Rule, is

A

B

C

D none of these.

ANS:A -

The transit rule is that which is applied when the angular measurement is more accurate than linear measurement. For correction of latitude or departure by transit rule, we can use this formula. 5.
(error in latitude X latitude of that side/ arithmetic sum of all traverses). If the error is dx then it is divided into equal parts.
Then it is dx/Σlat.
But the original latitude is l then correction is given by lx (dx/Σlat).
