gml:topoCurveProperty

The gml:topoCurveProperty property element may be used in features to express their relationship to the referenced topology edges.

Element information

Content

• gml:TopoCurve [1..1]gml:TopoCurve represents a homogeneous topological expression, a sequence of directed edges, which if realised are isomorphic to a geometric curve primitive. The intended use of gml:TopoCurve is to appear within a line feature to express the structural and geometric relationships of this feature to other features via the shared edge definitions. If provided, the aggregationType attribute shall have the value "sequence".
