CHECK ON CLOSED TRAVERSE
1. Check on angular measurements
(a) The sum of the measured interior
angles should be equal to (2N – 4) x 900 where N is the number of sides of the
traverse.
angles should be equal to (2N – 4) x 900 where N is the number of sides of the
traverse.
(b) The sum of the measured exterior
angles should be equal to (2N + 4) x 900.
angles should be equal to (2N + 4) x 900.
(c) The algebraic sum of the deflection
angles should be equal to 3600.
angles should be equal to 3600.
Right-hand deflection is considered
positive and left-hand deflection negative.
positive and left-hand deflection negative.
2. Check on
linear measurement
linear measurement
(a) The lines should be measurement once
each on two different days (along opposite directions). Both measurements
should tally.

(b) Linear measurements should also
be taken by the stadia method. The measurements by chaining and by the stadia
method should tally.
