Mistakes in Compass Traverse Work

Play an AI-generated podcast conversation about this lesson

Which mistake in compass work involves interchanging the recording of azimuths from north and south?

Interchanging magnetic and true bearings (correct)

Failing to adjust observed traverse angles

Selecting a line for referencing arbitrary directions

Mixing clockwise and counterclockwise angles

In compass traverse, what does the latitude of a line indicate?

Positive if direction is East, negative if West

Distance from the starting point

Direction of the bearing

Positive if direction is North, negative if South (correct)

What does the departure of a line indicate in surveying?

The length of the line

Positive if direction is West, negative if East (correct)

The deviation from the true north

Positive if direction is South, negative if North
