Marker Post - Spatial object type

Definition: Reference marker placed along a route in a transport network, mostly at regular intervals, indicating the distance from the beginning of the route, or some other reference point, to the point where the marker is located.

Description: EXAMPLE Examples of routes along which marker posts can be found are roads, railway lines and navigable waterways.

Subtype of: Transport Point


Attributes

Definition: Distance from the begi
ing of the route, or some other reference point, to the point where a marker post is located.

Valuetype: DateTime

Definition: A geographical name that is used to identify the transport network object in the real world. It provides a 'key' for implicitly associating different representations of the object.

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

Definition: External object identifier of the spatial object.

Description: NOTE An external object identifier is a unique object identifier published by the responsible body, which may be used by external applications to reference the spatial object. The identifier is an identifier of the spatial object, not an identifier of the real-world phenomenon.

Multiplicity: 0...1

Associated objects - Mandatory

Definition: A collection of transport link sequences and or individual transport links that has a specific function or significance in a transport network.

Description: NOTEThis spatial object type supports the aggregation of links to form objects with branches, loops, parallel sequences of links, gaps, etc.EXAMPLEA dual carriageway road, as a collection of the two link sequences that represent each carriageway.

Multiplicity: 1

Name of the association: route

Association definition: Route in a transport network along which the marker post is placed.
