gml:LineStringSegment

A LineStringSegment is a curve segment that is defined by two or more control points including the start and end point, with linear interpolation between them.
The content model follows the general pattern for the encoding of curve segments.

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

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

Type: gml:LineStringSegmentType

Properties: Global, Qualified

Content

Choice [1..1]
- 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.
  - gml:pointRep
- gml:posList
- gml:coordinates
