Geographical location indications (for Line 109, Oslo)

JourneyPattern

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

According to Nordic NeTEx Profile, the actual route must be defined as at the highest possible level in the XML structure, and in most cases, it is recommended that this be done as a set of Projeksjon#serviceLinks with Link projections describing the points it follows. These should unambiguously describe the path using sufficient GML coordinates (gml:pos) so that the line's JourneyPattern is correctly displayed on maps.

In some cases (e.g. air routes), this may be done using the line's RoutePoints, since it will suffice to display the route as a straight line between these two locations.

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

Link

The XML example in it its entirety can be found in the GitHub repository: https://github.com/entur/profile-norway-examples/blob/master/netex/Full_PublicationDelivery_109_Oslo_morningbus_example.xml

PublicationDelivery

Because other relevant data structures in the example have already been described in Simple rhythm based bus line / Simple bus line, only the definition of serviceLinks and their use in linksInSequence (in JourneyPattern) are described in this document.

serviceLinks

Projeksjon#serviceLinks with Link projections describes additional geographical points between StopPoints/TimingPoints .

linksInSequence

The links describing how to project the line's JourneyPattern are used in conjunction with the stops (possibly timing points) to accurately specify the line's JourneyPattern.
