Polygon

gml:Polygon

Defined in gml/gmlBasic2d-extract-v3_2_1-.xsd:60

A Polygon is a special surface that is defined by a single surface patch (see D.3.6). The boundary of this patch is coplanar and the polygon uses planar interpolation in its interior. The elements exterior and interior describe the surface boundary of the polygon.

        The value of this property is a remote text description of the object. The xlink:href attribute of the gml:descriptionReference property references the external description.

      • gml:identifiergmlBase-extract-v3_2_1.xsd:117 0..1 gml:CodeWithAuthorityType

        Often, a special identifier is assigned to an object by the maintaining authority with the intention that it is used in references to the object For such cases, the codeSpace shall be provided. That identifier is usually unique either globally or within an application domain. gml:identifier is a pre-defined property for such identifiers.

      • gml:namegmlBase-extract-v3_2_1.xsd:112 0..unbounded gml:CodeType

        The gml:name property provides a label or identifier for the object, commonly a descriptive name. An object may have several names, typically assigned by different authorities. gml:name uses the gml:CodeType content model. 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. In common usage there will be one name per authority, so a processing application may select the name from its preferred codeSpace.

  • gml:exteriorgmlBasic2d-extract-v3_2_1-.xsd:66 0..1 gml:AbstractRingPropertyType

    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:interiorgmlBasic2d-extract-v3_2_1-.xsd:71 0..unbounded gml:AbstractRingPropertyType

    A boundary of a surface consists of a number of rings. The "interior" rings separate the surface / surface patch from the area enclosed by the rings.
