Geographical location indications (for Line 109, Oslo)

Journeypattern

A JourneyPattern can be defined as pointsInSequence (a sorted list of points, detailed in other example) and / or linksInSequence (a sorted list of links between two points).

According to The Norwegian NeTEx Profile, the actual route must be defined as high as possible, and in most cases it is recommended that this be done as a set of 637370789 with  Link projections describing the points this follows. These should describe the path unambiguously using sufficient GML coordinates (gml: pos) so that the line's  JourneyPattern is correctly displayed in map services.

In some cases (eg, flight routes), this may alternatively be done by the line's RoutePoints, since it will suffice to display the route in maps as a straight line between these two locations.


See also officialNeTex White Papers, in particular 06.NeTEx-Network-WhitePaper, where this aspect is described in detail.

The entire XML sample file is located on the project's GitHub repository below https://github.com/entur/profile-norway-examples/blob/master/netex/Full_PublicationDelivery_109_Oslo_morningbus_example.xml

Because other relevant datastructures in the example have already been reviewed in Simple route - Bus (rhytmbased departure) (i arbeid) / Simple route - Bus (i arbeid), only definition of serviceLinks and their use in linksInSequence (in JourneyPattern) are reviewed in this document.

linksInSequence

The links describing how the line's journeypattern is to be projected onto maps are used in conjunction with the stops (possibly timing points) to accurately specify the line's JourneyPattern.
