The word azimuth came from Arabic origins, ‘as-sumut’, which is the plural of ‘as-samt’. It means – ‘the way or direction’. It is a determination of a direction with the use of a compass. (See bearing [..]

an obvious feature located beyond the desired point (control or other feature) that indicates that the target point has been overshot (passed by).

A bearing is described from north or south, and at what angle to the east or west. 20 degrees East of South (S 20 E) is a bearing. It is equivalent to an azimuth of 160 degrees.

an obvious (large) feature near the desired point that can be used an as attack point from which to find the control. Examples include ponds, cliffs, and most linear features.

is a long terrain feature such as a road, trail, stream, lake shore, fence line, or ridge line. When you follow a linear feature, it's often called a handrail.

a terrain feature (sometime called a draw) that is a continuous line of LOWER ground between two parallel (or at least adjacent) spurs. The area of low ground itself is the re-entrant. Re-entrants are [..]

a continuous sloping line of HIGHER ground, normally jutting out from the side of a larger ridge. A spur is often formed by two adjacent re-entrants. When standing on a spur, the ground slopes downwar [..]
