Attributes:
  • curveType: type of the horizontal curve, e.g. arc or clothoide or straight (obligatory; xs:string; patterns: other:\w{2,})
Possible values:
  • arc: An arc has a constant radius that is not infinite and not zero.
  • clothoide
  • cosinusoide
  • cubicParabola
  • curveBloss
  • curveWiener
  • doucine
  • sinusoide
  • straight: A straight curve has a constant radius that is infinite.,

  • azimuth: constant azimuth (direction angle) of the horizontal curve in degrees;
    Direction "north" has an azimuth of 0 degrees, "east" 90, "south" 180 and "west" 270 degrees. (optional; xs:decimal),

  • deltaAzimuth: change of azimuth of the horizontal curve in degrees;
    use this attribute if the azimuth of the horizontal curve is not constant, but changing;
    delta azimuth shall be calculated as difference of azimuth value at the end and the azimuth value at the beginning of the horizontal curve. (optional; xs:decimal),

  • radius: radius of the horizontal curve in meters;
    use value "0" (zero) to describe straight curves with infinite radius;
    use negative values to describe a horizontal curve going to the left (as seen from begin of curve) and use positive values to describe a horizontal curve going to the right (as seen from begin of curve) (optional; xs:decimal),

  • length: length of the horizontal curve in metres;
    for arcs and transition curves (e.g. clothoides) this attribute defines the arc length (optional; xs:decimal),

  • id: the identifier of the object; this can be either of type xs:ID or UUID (obligatory; xs:string; patterns: (urn:uuid:)?[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}|\{[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}\})
*Notice:
Elements may have different parent elements. As a consequence they may be used in different contexts.
Please, consider this as well as a user of this wiki as when developing this documentation further.
Aspects that are only relevant with respect to one of several parents should be explained exclusively in the documentation of the respective parent element.
