gml:BaseUnitType

Definition of a unit of measure which is a base unit from the system of units.  A base unit cannot be derived by combination of other base units within this system.  Sometimes known as "fundamental unit".  

Complex type information

Content

• Sequence [1..1]
  from type gml:DefinitionType
  gml:metaDataProperty [0..*]    Contains or refers to a metadata package that contains metadata properties.
  gml:description [0..1]    Contains a simple text description of the object, or refers to an external description.
  Choice [1..*]
  from subst. group gml:name
  gml:name    Label for the object, normally a descriptive name. An object may have several names, typically assigned by different authorities. The authority for a name is indicated by the value of its (optional) codeSpace attribute. The name may or may not be unique, as determined by the rules of the organization responsible for the codeSpace.
  gml:csName    The name by which this coordinate system is identified.
  gml:coordinateOperationName    The name by which this coordinate operation is identified.
  gml:methodName    The name by which this operation method is identified.
  gml:parameterName    The name by which this operation parameter is identified.
  gml:groupName    The name by which this operation parameter group is identified.
  gml:datumName    The name by which this datum is identified.
  gml:meridianName    The name by which this prime meridian is identified. The meridianName most common value is Greenwich, and that value shall be used when the greenwichLongitude value is zero.
  gml:ellipsoidName    The name by which this ellipsoid is identified.
  gml:srsName    The name by which this reference system is identified.
  from type gml:UnitDefinitionType
  gml:quantityType [1..1]    Informal description of the phenomenon or type of quantity that is measured or observed. For example, "length", "angle", "time", "pressure", or "temperature". When the quantity is the result of an observation or measurement, this term is known as Observable Type or Measurand.
  gml:catalogSymbol [0..1]    For global understanding of a unit of measure, it is often possible to reference an item in a catalog of units, using a symbol in that catalog. The "codeSpace" attribute in "CodeType" identifies a namespace for the catalog symbol value, and might reference the catalog. The "string" value in "CodeType" contains the value of a symbol that is unique within this catalog namespace. This symbol often appears explicitly in the catalog, but it could be a combination of symbols using a specified algebra of units. For example, the symbol "cm" might indicate that it is the "m" symbol combined with the "c" prefix.
