Parents* gradientCurves
Children any (0..*), areaLocation (0..*), beginsInGeometryPoint (0..1), endsInGeometryPoint (0..1), gmlLocations (0..*), isValid (0..*), linearLocation (0..*), name (0..*), networkLocation (0..*), spotLocation (0..*)
Attributes:
  • curveType: type of vertical curve, e.g. arc or straight (obligatory; xs:string)
Possible values:
  • arc: curve with a constant radius that is not infinite
  • mixed: an aggregated curve with arcs and straight parts
  • straight: curve with constant infinite radius (zero curvature),

  • gradient: constant gradient of the gradient curve in per million;
    positive values indicate an upward slope (rise), negative values indicate a downward slope (fall) (optional; xs:decimal),

  • deltaGradient: change of gradient of the gradient curve in per million;
    use this attribute if the gradient value of the gradient curve is not constant, but changing;
    the delta gradient shall be calculated as difference of gradient at the end and gradient at the beginning of the gradient curve (optional; xs:decimal),

  • radius: radius of the gradient curve in metres;
    use negative values to describe the arc curve of a valley and use positive values to describe the arc curve of a hill (optional; xs:decimal),

  • length: length of the gradient curve in metres;
    use this attribute in particular to define 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.
