deletionDate

Date

The date the feature was deleted from the Ordnance Survey maintenance database.

descriptiveGroup

String

This is the primary classification attribute of a feature.

descriptiveTerm

String

This attribute, if present, gives further classification information about the feature.

point

Point

A pair of easting and northing co-ordinates in metres, defining a location in the British National Grid spatial reference system.

reasonForChange

String

The reason for a change made to a feature. Forms part of the feature’s complex attribute changeHistory.

reasonForDeparture

String

This is set to ‘Deleted’ or ‘Vacated’ to indicate whether a feature has physically been deleted from the database or is no longer relevant due to change in COU supply. *

theme

String

A theme that the feature belongs to.

TOID

TOID

The unique 16-digit reference number of a feature. Prefixed with ‘osgb’ to comply with XML identifier rules.

version

Integer

The version number of the feature (in the range 1 to 4294967295). This uniquely identifies a specific version of a feature with a given TOID.

versionDate

Date

The date on which this version of the feature became the current version. This is the date on which the feature was changed in the database and is not the date of any associated real-world change.

*ITN Urban Paths themedoes not contain Change-Only Update within the current version of the product but will be introduced at a later stage.

Road type

Description

Motorway

A multi-carriageway public road connecting important cities, always numbered and with no addresses.

A road

A public road, classified as an A road by the DfT, connecting areas of regional importance, always numbered, sometimes named, often with addresses.

B road  

A public road, classified as a B road by the DfT, connecting places of local significance, always numbered, sometimes named, often with addresses.

Minor road

A public road without a DfT classification of motorway, A or B that connects the roads defined below to B and higher classification roads*.

In urban areas usually named, often with addresses. In rural areas sometimes named and sometimes with addresses.

Local street

A public road that provides access to land and/or houses, usually named with addresses. Generally not intended for through traffic*.

Alley

A road without access restrictions that provides alternate/secondary vehicular access to land or houses. They may be named but are usually without addresses. They are usually not intended for through traffic, though they may be accessible from more than one location.

Typical examples are those that run behind rows of houses.

Currently, coverage is limited to roads formerly described as ‘Private’ in previous Ordnance Survey road products but reclassified following ground visits.

Private road – publicly accessible

A privately-maintained road or a road within a property boundary where publicly access by the public is considered usual for at least some part of the day. For example, a road within a hospital, sports centre or school.

They may extend through a site if more than one entrance exists. If only one entrance exists they are normally created to extend to the principal building within a single site or the boundary of the last property served for features accessing more than one addressed or otherwise identifiable property*.

They may be captured outside this definition if required to provide restricted connectivity to a track or path.

Private road – restricted access

A privately maintained road or a road within a property boundary where access by the public is restricted by physical (for example, gate) or administrative (for example, sign) means or is not considered usual. For example, roads within a military base, an oil refinery, within a private residential garden or leading to two private properties*.

Such roads are captured only where they exceed 100 m in length or serve more than one addressed or otherwise identifiably separate property.

Roads are normally created to extend to the principal building within a single site or the boundary of the last property served for roads serving multiple properties. Two exceptions to this exist:

• where a track or path exists that the road is connected to, the road must be extended to that point
• where roads within a private residential garden extend for more than 100 m from the property boundary

Pedestrianised street

Roads that have been altered for use principally by pedestrians but may street provide some access for certain types of vehicle*.

Details of specific routing access restrictions will be within the RRI theme.

Definition

Single carriageway

Default link type.

A road consisting of a single carriageway with traffic in one or both directions. There may be more than one lane in any particular direction.

Dual carriageway

A road consisting of two separate carriageways with separate flow directions. The carriageways are partitioned by physical features, such as a barrier and/or verge.

Slip road

An exit or entry point to and from the major road network, including motorways.

Roundabout

A method of controlling traffic flow by allowing vehicles from a particular direction priority.

Enclosed traffic area

Car parks and similar areas through which traffic passes but are not generally considered to be a road. Only the entrances and exits of car parks will be captured.

Traffic island link at junction

Where an island over 8 m² exists in the middle of a road on the approaches to a junction, the RoadLink is split around it. The split links will carry this attribute value.

Traffic island link

Where an island over 8 m² exists in the middle of a road, the RoadLink is split around it. The split links will carry this attribute value.
