				The properties of Resolution are listed below.
| Identifier | Title / Description | Value Domain | Card | 
|---|---|---|---|
| equivalentScale [DMF/Core] | Equivalent Scale Level of detail expressed as the scale of a comparable hardcopy map or chart. Constraints:* It is mandatory to provide one of equivalentScale, distance, vertical or levelOfDetail. 
 | integer | 0..1 | 
| distance [DMF/Core] | Ground Sample Distance Horizontal ground sample distance of the resource (typically for gridded data and imagery-derived products). A resolution distance shall be expressed as a distance. Note: Not applicable to non-geographic data. This element is used to give a general overview of the resolution of the data. If more accurate resolution elements are needed they can be encoded as quality results. Constraints:* It is mandatory to provide one of equivalentScale, distance, vertical or levelOfDetail. 
 | distance | 0..1 | 
| vertical [DMF/Common] | Vertical Vertical sampling distance. Constraints:* It is mandatory to provide one of equivalentScale, distance, vertical or levelOfDetail. 
 | Distance | 0..1 | 
| levelOfDetail [DMF/Common] | Level of detail Brief textual description of the spatial resolution of the resource. Constraints:* It is mandatory to provide one of equivalentScale, distance, vertical or levelOfDetail.
