A quantitative measure of a physical property that determines the non-geospatial characteristics or behavior of something. Geospatial refers to placement or shape relative to the surface of the earth. A combination of a dimension value, dimension type, and relevant unit of measure is used to define or describe the subject. For example if the subject of a dimension is the wall of a building, a dimension is used to record an aspect (height) of the wall as follows: Dimension value: 10; unit of measure: Feet; dimension type: Height. The unit of measure of a purely scalar dimension, such as specific gravity, is "None". |
