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.

(also ded (for deduced) reckoning) is the process of calculating one's current position by using a previously determined position, and a known (estimated) speed and heading.

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 [..]

is the process of figuring out where you are by finding the intersection of two bearings to distant known features. See the post on triangulation.
