gml:DirectPositionType

geometryBasic0d1d.xsd

DirectPosition instances hold the coordinates for a position within some coordinate reference system (CRS). Since 
			DirectPositions, as data types, will often be included in larger objects (such as geometry elements) that have references to CRS, the 
			"srsName" attribute will in general be missing, if this particular DirectPosition is included in a larger element with such a reference to a 
			CRS. In this case, the CRS is implicitly assumed to take on the value of the containing object's CRS.

Attributes

Name	Occ	Type	Description	Notes
srsName	[0..1]	xsd:anyURI	In general this reference points to a CRS instance of gml:CoordinateReferenceSystemType (see coordinateReferenceSystems.xsd). For well known references it is not required that the CRS description exists at the location the URI points to. If no srsName attribute is given, the CRS must be specified as part of the larger context this geometry element is part of, e.g. a geometric element like point, curve, etc. It is expected that this attribute will be specified at the direct position level only in rare cases.	from group gml:SRSReferenceGroup
srsDimension	[0..1]	xsd:positiveInteger	The "srsDimension" is the length of coordinate sequence (the number of entries in the list). This dimension is specified by the coordinate reference system. When the srsName attribute is omitted, this attribute shall be omitted.	from group gml:SRSReferenceGroup
