Reference point

A reference point is tool used for the purpose of striking systematic comparisons of states relative to a controlled state.

Through its use, a tool offers all observers a common Frame of reference through which to judge change and from which to establish its significance.

Reference points are also employed when giving directions. A reference point is the location from which the directions start, or the position from which other objects' distances are measured. For example, if Building B was to the left of Building A, then one would use Building A as a reference point, and say go to the left of Building A in order to reach Building B. Intermediate reference points - commonly known as "waypoints" or "control points", are positions along a path of travel used to verify how accurately the path has been navigated.

When using displacement, moving away from the reference point and then returning to it means you will still be facing the same direction and be in the same location. You can also use the reference point to locate distance.
