RoutingPoint

This section defines the attributes associated with the RoutingPoint feature. It is important to note that UML notation has been used to show the multiplicity for an attribute. These indicate whether an attribute is optional (0), has a single value (1), or can have either / or (0..1) where ‘or’ is represented by double dots (..).

RoutingPoint attributes

RoutingPoint

Subtype of: Node, TransportNode

The spatial object type defining point/node feature, which would normally lie on a Highways RoadLink and would be referenced by a particular access point.

geometry

The coordinate geometry defining the position of the routingPoint. The geometry is projected in two-dimensions (2D).

• Attribute Name: geometry

• Value type: GM_Point

• Size: One coordinate set

• Multiplicity: [1]

toid

A unique identifier for a routingPoint, which is maintained along with the version number and version date to reflect the life cycle of the feature. NOTE: equivalent to INSPIRE identifier.

• Attribute Name: toid

• Value type: Text

• Size: 20

• Multiplicity: [1]

version

The version number of the data representation of the persisting routingPoint feature.

• Attribute Name: version

• Value type: Integer

• Size: 3

• Multiplicity: [1]

versionDate

The date on which the current version of the routingPoint was created.

• Attribute Name: versionDate

• Value type: Date

• Size: NA

• Multiplicity: [1]

reasonForChange

Reason for the current version of the routingPoint to be created. The valid reasons for change are defined in the ReasonForChangeValue code list.

• Attribute Name: reasonForChange

• Value type: ReasonForChangeValue

• Size: 20

• Multiplicity: [1]

refToITNRoadLink

The unique identifier (TOID) of the Highways road link feature that the routingPoint is related to.

• Attribute Name: refToITNRoadLink

• Value type: Text

• Size: 20

• Multiplicity: [1]

itnRoadLinkVersionDate

The date on which the current version of the Highways Road Link was created. A default value of ‘1900-01-01’ will be used to indicate where the date of this feature has not been captured.

• Attribute Name: itnRoadLinkVersionDate

• Value type: Date

• Size: NA

• Multiplicity: [1]

startDistance

The distance (m) from the start of the referenced Network RoadLink feature to the vertex where the RoutingPoint is positioned. The startDistance is calculated in two-dimensions (2D).

• Attribute Name: startDistance

• Value type: Length

• Size: 7.2

• Multiplicity: [1]
