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.
Streets are attributed with an “operationalState” with a data type of “OperationalStateType”. The attribution of this data type is detailed below.
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]
If known, the real-world start and end date/times when the state applies.
Attribute name: validTime
Type: TM_Period
Multiplicity: [0..1]
When a street has been closed a short description of the reason for closure.
Attribute name: reason
Type: CharacterString
Size: 120
Multiplicity: [0..1]
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.
An external unique object identifier published by the responsible body may be used by external applications to reference the spatial object.
The local identifier is unique within the namespace, that is no other spatial object carries the same unique identifier.
Attribute name: localId
Type: CharacterString
Size: 16
Multiplicity: [1]
Namespace uniquely identifying the data source of the spatial object.
Attribute name: namespace
Type: CharacterString
Size: 18
Multiplicity: [1]
RoadLink, Road and Street are attributed with a “designatedName” with a data type of “DesignatedNameType”. The attribution of this data type is detailed below.
The name assigned to the road or street by a designated Street Naming Authority.
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]
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.
The authority responsible for the street naming and numbering or maintenance.
The code used to identify the authority. Example: 0114
Attribute name: identifier
Type: CharacterString
Size: 4
Multiplicity: [1]
Official name of the authority. Example: Bath and North East Somerset
Attribute name: authorityName
Type: CharacterString
Size: 100
Multiplicity: [1]
Total increase in height experienced when passing along the link from the start to the end.
Attribute name: inDirection
Type: Measure
Multiplicity: [1]
Total increase in height experienced when passing along the link from the end to the start.
Attribute name: inOppositeDirection
Type: Measure
Multiplicity: [1]
A RoadLink could be attributed with “cycleFacility” with a data type of “CycleFacilityType”. The attribution of this data type is detailed below.
The cycle amenity available along the link.
Attribute name: cycleFacility
Type: CycleFacilityValue
Size: 45
Multiplicity: [1]
Identifies if the facility applies to entirety of the link.
Attribute name: wholeLink
Type: Boolean
Size: 5
Multiplicity: [1]
The name of the attribute and what it is describing.
The nature of the attribute, for example a numeric value or a code list value.
The length of the attribute provided (optional).
Describes how many times this element is expected to be populated in the data. An attribute may be optional or mandatory within the product. These are denoted by:
‘1’ – there must be a value.
‘0..1’ – population is optional but a maximum of one attribute will be returned These values may be used in combination.
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.
The average width of the road carriageway.
Attribute name: averageWidth
Type: Measure
Multiplicity: [1]
The minimum width of the topographic area feature the RoadLink is representing.
Attribute name: minimumWidth
Type: Measure
Multiplicity: [0..1]
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]
