The direction along the Earth's surface towards the geographic North Pole.

The difference between True North and Magnetic North is called:

A positive declination occurs when Magnetic North is ……. of True North.

A negative declination occurs when Magnetic North is ……. of True North.

If the Magnetic bearing = 215º 00' and Declination = 2° 00' W, Then, True bearing =

This system measures the horizontal angle from the north direction to the line in a clockwise direction.

The effect of nearby magnetic influences distorts a compass reading, causing the compass needle to deviate from pointing toward Magnetic North.

A local attraction is suspected if ..

A series of connected survey lines between a series of points, which are used to determine positions, distances, and angles.

The traverse starts at one known control point and ends at another known control point, often following a linear or semi-linear path.

Tolerance of angular closing error of a closed traverse is determined by

Angular closing error of a closed traverse equals ….

If the angular closing error of a five-sided traverse is + 2º 30', then the correction to each angle is

The main purpose of graphical scale is
