List of top Geomatics Engineering Questions on Traversing and triangulation survey asked in GATE CE

The Whole Circle Bearing (WCB) of line AB is \(150^{\circ}\). The length of AB is 100 m. The latitude and departure values, respectively, for this line are:

If the number of sides resulting in a closed traverse is increased from three to four, the sum of the interior angles increases by

Traversing is carried out for a closed traverse PQRS. The internal angles at vertices P, Q, R, and S are measured as 92°, 68°, 123°, and 77°, respectively. If fore bearing of line PQ is 27°, fore bearing of line RS (in degrees, in integer) is \(\underline{\hspace{1cm}}\).

For a given traverse, latitudes and departures are calculated and it is found that sum of latitudes is equal to +2.1 m and the sum of departures is equal to -2.8 m. The length and bearing of the closing error, respectively, are
