  1. [physics] A length of a certain distance and bearing.
  2. [physics] The area over which an entity extends.
  3. [spatial analysis] A measure of spatial extent, especially width, height, or length. A point has zero dimensions, a line has one dimension, a plane or polygon has two dimensions, and a feature with volume has three dimensions.
  4. [physics] The number of axes that are essential to the existence of an entity in space. For example, the identity of a location on a plane requires two axes; therefore, a plane exists in the second dimension, and an entity with two axes, or dimensions, may be uniquely identified as a plane.
