The Identifier is an INSPIRE data type and its elements make up the “inspireId” attribute which can be found across all feature types in the OS MasterMap Highways Network.

Identifier attributes

An external unique object identifier published by the responsible body may be used by external applications to reference the spatial object.

localId

The local identifier is unique within the namespace, that is no other spatial object carries the same unique identifier.

This section describes the structured data types which make up OS MasterMap Highways Network - Roads. The attributes associated with these data types are listed below along with a brief description of their data properties.

RoadLink, Road and Street are attributed with a “designatedName” with a data type of “DesignatedNameType”. The attribution of this data type is detailed below.

DesignatedNameType attributes

The name assigned to the road or street by a designated Street Naming Authority.

name

Official name assigned to the highway by a designated Street Naming Authority. Note: Where a feature has more than one name, the language of each name is provided as a 3-digit ISO 639-2 code (‘eng’, ‘cym’, ‘gla’).

• Attribute name: name

• Type: LocalisedCharacterString

• Size: 255

• Multiplicity: [1]

namingAuthority

The local authority that assigned the designatedName.

• Attribute name: namingAuthority

• Type: ResponsibleAuthority

• Multiplicity: [1]

RoadLink and Street are attributed with “designatedName” and Street is attributed with a “responsibleAuthority” with a data type of “ResponsibleAuthority”. The attribution of this data type is detailed below.

ResponsibleAuthority attributes

The authority responsible for the street naming and numbering or maintenance.

identifier

The code used to identify the authority. Example: 0114

• Attribute name: identifier

• Type: CharacterString

• Size: 4

• Multiplicity: [1]

authorityName

Official name of the authority. Example: Bath and North East Somerset

• Attribute name: authorityName

• Type: CharacterString

• Size: 100

• Multiplicity: [1]

Streets are attributed with an “operationalState” with a data type of “OperationalStateType”. The attribution of this data type is detailed below.

OperationalStateType attributes

state

Indicator identifying the physical nature of the road, e.g. Under Construction, as reported by the highway authority.

• Attribute name: state

• Type: OperationalStateValue

• Size: 19

• Multiplicity: [1]

validTime

If known, the real-world start and end date/times when the state applies.

• Attribute name: validTime

• Type: TM_Period

• Multiplicity: [0..1]

reason

When a street has been closed a short description of the reason for closure.

• Attribute name: reason

• Type: CharacterString

A RoadLink could be attributed with “cycleFacility” with a data type of “CycleFacilityType”. The attribution of this data type is detailed below.

CycleFacilityType attributes

cycleFacility

The cycle amenity available along the link.

• Attribute name: cycleFacility

• Type: CycleFacilityValue

• Size: 45

• Multiplicity: [1]

wholeLink

Identifies if the facility applies to entirety of the link.

• Attribute name: wholeLink

• Type: Boolean

• Size: 5

• Multiplicity: [1]

A RoadLink could be attributed with “roadWidth” with a data type of “RoadWidthType”. The attribution of this data type is detailed below. This value is based upon the Topographic Area features supplied in OS MasterMap Topography Layer and must not be used to indicate if a vehicle of a specific width can use a particular section of road.

RoadWidthType attributes

averageWidth

The average width of the road carriageway.

• Attribute name: averageWidth

• Type: Measure

• Multiplicity: [1]

minimumWidth

The minimum width of the topographic area feature the RoadLink is representing.

• Attribute name: minimumWidth

• Type: Measure

• Multiplicity: [0..1]

confidenceLevel

Records the original capture specification for the OS MasterMap Topography layer feature used to indicate the width of the carriageway. This provides an indication of the confidence that can be placed in the value provided.

• Attribute name: confidenceLevel

• Type: RoadWidthConfidenceLevelValue

• Size: 27

• Multiplicity: [1]
