Scheme description / Schemenbeschreibung
Position of point in the XML-Tree / Position von point im XML-Baum
- Parent: <polygon>
- Children: None
Multiplicity / Anzahl
Semantics / Bedeutung
Specification of the polygon by its bounding nodes; first and last point are connected to close the polygon.(introduced with version 2.5)
Attributes of point / Attribute von point
- coord: This is a list of values representing the coordinates.
- extraHeight: This is a separate value for the altitude/height. It is used: 1) if altitudes are stored in an own reference system (i. e. epsgCode refers to a GeodeticCRS rather than a CompoundCRS); 2) if there are no long/lat coords given or known but a height. See <geoCoord> for further notes.
- epsgCode: This is an URI pointing to the EPSG-Code (external link) as reference system for the coordinates in coord.
- heightEpsgCode: This is an URI pointing to the EPSG-Code (external link) for the separate altitude reference system.
Syntactic Constraints / Syntaktische Beschränkungen
- coord: Restriction of tDoubleList, a coordinate list consisting of two or three coordinates. Required
- extraHeight: xs:double, optional
- epsgCode: xs:anyURI, optional
- heightEpsgCode: xs:anyURI, optional
