gml:CircleByCenterPoint

A gml:CircleByCenterPoint is an gml:ArcByCenterPoint with identical start and end angle to form a full circle. Again, this representation can be used only in 2D.

Element information

Namespace: http://www.opengis.net/gml/3.2

Schema document: external/ogc/gml/3.2.1/geometryPrimitives.xsd

Type: gml:CircleByCenterPointType

Properties: Global, Qualified

Content

Sequence [1..1]
1. Choice [1..1]
  - gml:pos
  - gml:pointPropertyThis property element either references a point via the XLink-attributes or contains the point element. pointProperty is the predefined property which may be used by GML Application Schemas whenever a GML feature has a property with a value that is substitutable for Point.
  - gml:pointRep
  - gml:posList
  - gml:coordinates
2. gml:radius [1..1]
