LOC Location
To describe the location in space and time of the axis of an item relative to an origin axis; euclidian geometry has been assumed with orthogonal axes; the sequence of axes has been chosen in the customary sequence of X, Y, and Z; however, it is possible to just use two dimensional space rather than three
