gml:PolygonType
geometryBasic2d.xsd
A Polygon is a special surface that is defined by a single surface patch. The boundary of this patch is coplanar and the polygon uses planar interpolation in its interior. It is backwards compatible with the Polygon of GML 2, GM_Polygon of ISO 19107 is implemented by PolygonPatch.

Content
- Sequence [1..1]
- 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 [0..*]
- 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 subst. group gml:name - gml:exterior [0..1] A boundary of a surface consists of a number of rings. In the normal 2D case, one of these rings is distinguished as being the exterior boundary. In a general manifold this is not always possible, in which case all boundaries shall be listed as interior boundaries, and the exterior will be empty.
- gml:interior [0..*] A boundary of a surface consists of a number of rings. The "interior" rings seperate the surface / surface patch from the area enclosed by the rings.

| Name | Occ | Type | Description | Notes |
|---|---|---|---|---|
| gml:id | [0..1] | xsd:ID | from type gml:AbstractGMLType | |
| 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 |
