Test: Traverse Surveying & Contouring - 1 - Civil Engineering (CE) MCQ

The Bowditch method of adjusting a traverse is based on the assumption that

where e₁ and e₂ are errors in linear and angular measurements respectively and l is the length of a line

Accuracy of elevation of various points obtained from contour map is limited to

If L is the perimeter of a closed traverse, ΔD is the closing error in departure, the correction for the departure of a traverse side of length l, according to Bowditch rule, is

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

If the reduced bearing of a line AB is N60°W and length is 100 m, then the latitude and departure respectively of the line AB will be

If the sum of northings of a traverse exceeds the sum of southings by 1 m and sum of eastings exceeds the sum of westirigs by 1 m, the resultant closing error and its true bearing respectively are

In a closed traverse, the sum of south latitudes exceeds the sum of north latitudes and the sum of east departures exceeds the sum of west departures. The closing line will lie in the
