<p>An area with the same geophysical parameter (temperature, pressure, humidity,..) value or value range at a specific time. The truth value of this statement is not considered here, value may be speculative (forecast). The main intention for objects of this type is to represent observed and forecast parameter values on a map.</p><p>Area may contain zero or more inner areas with a different set of geophysical parameter values. This kind of hierarchical areas are defined for describing gradual changes in the parameter values within an area.</p>
The attribute gml:id supports provision of a handle for the XML element representing a GML Object. Its use is mandatory for all GML objects. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs.
