FUNDAMENTAL SURVEYING Traversing and Coordinate Geometry

Question 1

Which traverse adjustment method distributes closure errors in proportion to the length of each side?

Accepted Answer

Bowditch (Compass) Rule

Answer

The Bowditch (Compass) Rule distributes latitude and departure errors proportionally to the length of each traverse course.

Question 2

In the Transit Rule for traverse adjustment, corrections are distributed proportionally to:

Accepted Answer

The latitude and departure of each side

Answer

The Transit Rule distributes latitude errors proportional to each side's latitude and departure errors proportional to each side's departure.

Question 3

What coordinate system uses Northing and Easting values referenced to a defined origin?

Accepted Answer

Cartesian (rectangular) coordinates

Answer

Cartesian (rectangular) coordinate systems express positions as Northing (Y) and Easting (X) measured from a defined origin.

Question 4

To compute the area of a traverse using the coordinate method, which formula is used?

Accepted Answer

DMD (Double Meridian Distance) method or coordinate cross-multiply method

Answer

The DMD method or coordinate method (cross-multiply formula) is used to compute the area enclosed by a traverse.

Question 5

A closed traverse has latitudes summing to +0.08 ft and departures summing to −0.06 ft. What correction is applied to each latitude?

Accepted Answer

The latitude correction for each course is proportional to the course's latitude in the Bowditch adjustment

Answer

In the Bowditch rule, each course's latitude correction = (course length / total perimeter) × total latitude error.
