Schema document: external/ogc-gml/3.1.1/dhs-gmo/1.0.0/gml.xsd

Properties: Global, Qualified

Content

Sequence [1..1]
1. gml:pos [1..1]
2. gml:radius [1..1] The radius of the arc.
3. gml:startAngle [0..1] The bearing of the arc at the start.
4. gml:endAngle [0..1] The bearing of the arc at the end.

Attributes

Name	Occ	Type	Description	Notes
interpolation	[0..1]	gml:CurveInterpolationType	The attribute "interpolation" specifies the curve interpolation mechanism used for this segment. This mechanism uses the control points and control parameters to determine the position of this curve segment. For an ArcByCenterPoint the interpolation is fixed as "circularArcCenterPointWithRadius".	Fixed value is "circularArcCenterPointWithRadius".
numArc	[1..1]	xsd:integer	Since this type describes always a single arc, the attribute is fixed to "1".	Fixed value is "1".
