gml:directedTopoSolid

The gml:directedSolid property element describes the coBoundary of topology faces and is used in the support of volume features via the gml:TopoVolume expression, see below. The orientation attribute of type gml:SignType expresses the sense in which the included solid appears in the face coboundary. In the context of a gml:TopoVolume the orientation attribute has no meaning.

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

Type: gml:DirectedTopoSolidPropertyType

Properties: Global, Qualified

Content

gml:TopoSolid [0..1]gml:TopoSolid represents the 3-dimensional topology primitive. The topological boundary of a solid (gml:directedFace) consists of a set of directed faces. A solid may optionally be realised by a 3-dimensional geometric primitive (gml:solidProperty).
