A short alias of the Parameter, identical to the one used as key in Coverage.parameters.
A LanguageMap object with a textual, perhaps lengthy, description of the parameter.
An ObservedProperty object.
An optionally defined object with the properties symbol and optionally label. symbol is an object with the properties value and optionally type where both are strings with value the unit string, for example "°C", and type a URI identifying the coding scheme, for example "http://www.opengis.net/def/uom/UCUM/". label is a LanguageMap object, for example {en: "Degrees Celsius"}. If the unit property is not defined, then the parameter values are unitless.
An optionally defined Map
object where each key is a Category ID, and each value an array of integers where each integer is unique within this map.
This property is used to relate categories encoded as numbers in coverage range values to their actual Category.
Note that a parameter object cannot have both unit and observedProperty.categories/categoryEncoding properties.
