ConnectingLink

The Road and Path Network are topologically structured together. ConnectingLinks enable a connection between the Road Network and the Path Network. A ConnectingLink feature is a linear spatial object which represents a logical connection between the Path Network and the Road Network; it does not represent a feature in the real world. A ConnectingLink will always reference a PathNode and a ConnectingNode. The context diagram below shows how the ConnectingLink relates to PathNode and ConnectingNode.

Three-dimensional geometry has been given to ConnectingLink features. This is to facilitate routing that requires coincidence of co-ordinates. Given the nature of connecting feature, this geometry is for connectivity purposes only.

ConnectingLink Attributes

A ConnectingLink is not a representation of a real-world object. It is a logical indicator of the connection between the Path Network and the Road Network.

id

Unique identifier; for ConnectingLink, this is a TOID.

• Attribute name: gml_id (GML), Toid (GeoPackage), toid (Vector Tiles)

• Type: CharacterString

• Size: 20

• Multiplicity: [1]

identifier

Uniform Resource Identifier.

• Attribute name: identifier (GML), identifier (GeoPackage), Not provided (Vector Tiles)

• Type: CharacterString

• Size: 37

• Multiplicity: [1]

inspireId INSPIRE

External object identifier of the spatial object.

• Attribute name: inspireId

• Type: Identifier

• Multiplicity: [0..1]

beginLifespanVersion INSPIRE

Date and time at which this version of the spatial object was inserted or changed in the spatial data set.

The time part is always set to zero.

• Attribute name: beginLifespanVersion

• Type: DateTime

• Multiplicity: [1]

reasonForChange

The reason for a change made to a feature.

• Attribute name: reasonForChange (GML), reason_for_change (GeoPackage), Not provided (Vector Tiles)

• Type: ChangeValue

• Size: 32

• Multiplicity: [1]

geometry

The implied connection between the RoadLink and the PathLink. Note, this is represented as a three-dimensional geometry to facilitate connectivity, but it is a logical connection not a physical alignment.

• Attribute name: geometry

• Type: GM_Curve

• Multiplicity: [1]

fictitious

Indicator that the geometry of the link is a straight line with no intermediate control points – unless the straight line represents the geography in the resolution of the data set appropriately.

• Attribute name: fictitious (GML), fictitious (GeoPackage), Not provided (Vector Tiles)

• Type: Boolean

• Size: 5

• Multiplicity: [1]

connectingNode

A reference to the ConnectingNode which the ConnectingLink references.

• Attribute name: connectingNode_href (GML), connecting_node (GeoPackage), Not provided (Vector Tiles)

• Size: 20

• Multiplicity: 1

pathNode

A reference to the PathNode which the ConnectingLink references.

• Attribute name: pathNode_href (GML), path_node (GeoPackage), Not provided (Vector Tiles)

• Size: 20

• Multiplicity: 1
