| | ELEMENT: COVERAGE |
 | | The Coverage element describes the spatial and temporal characteristics of the object or resource and is the key element for supporting spatial or temporal range searching on document-like objects that are georeferenced or time-referenced. |
 | | This element may be used in describing resources from many different fields, e.g., archaeology, art, cartography, geography, geographic information systems, medicine, natural sciences, etc. - any field that deals with georeferenced information, spatial data, or time-referenced data. |
 | | The values may be: a longitude/latitude pair (for a point); a set of four longitude/latitude values for a bounding box (in the order westernmost longitude, easternmost longitude, northernmost latitude, southernmost latitude); or a set of n longitude/latitude values for any polygon or for a line. |
