SamplingPointFinder

This filter projects the track onto the street map by creating a sampling point list for each track point. For more information we recommend reading the chapter Track point projection.

Input

• mandatory

  • PointList

  • SegmentList

  • TravelDirectionList

• optional (mutually exclusive - only one of the following may be given) :

  • HeadingList

  • PartialHeadingList

Output

• SamplingPointList

Configuration

• selectionStrategy: SelectionStrategy

  • one of the values in [all, best, single]

  • all: all candidates are added to the sampling point

  • best: only the best candidate is added to the sampling point (see Candidate search)

  • single: the sampling point is only considered when exactly one candidate is found, which is added

• searchRadius: [m] floating-point

  • Value is implicitly used to determine the maximum distance a track point can have from a street segment, it is however not used as a ‘radius’.

• maxHeadingDifference: [degree] floating-point

  • allowed heading difference between a track point and the corresponding candidate (the heading of a candidate depends on the street segment it is projected onto and the driving orientation)

  • only used if heading data is available
