gml:GeodesicString
A sequence of geodesic segments. The number of control points shall be at least two. interpolation is fixed as "geodesic". The content model follows the general pattern for the encoding of curve segments.
Element information
Namespace: http://www.opengis.net/gml/3.2
Schema document: external/ogc/gml/3.2.1/geometryPrimitives.xsd
Type: gml:GeodesicStringType
Properties: Global, Qualified
Content
- Choice [1..1]
- gml:posList
- Choice [2..*]
- 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.
