There have been small enhancements to the OS MasterMap Highways Network. This section will outline the main changes to the Road Network product. For changes to the Routing and Asset Management Information product, please see the Routing and Asset Management Information Technical Specification.
RoadJunction feature has been populated.
RoadLink and RoadNode ‘z’ values have been enhanced to reduce discrepancies when the road passes over a structure, for example, a bridge.
The “OperationalState” attribute on the Street features has introduced a new value, “Addressing Only”, into the “OperationalStateValue” codelist.
Corrected wrong multiplicity value for minimum width attribute within the “RoadWidthType” Data Type. This had the incorrect value of ‘1’ this has been corrected to ‘0..1’.
The OS MasterMap Highways Network – Roads can be ordered as either Full Supply or Change Only Update. The GeoPackage and vector tiles files are full GB coverage so are not available as a COU. The GML structures for Full Supply and COU are different. The differences are fundamentally the open and closing tags which will have an impact on how you choose to load the product. Examples of the different opening and closing tags can be found on the GML examples page. If a customer wishes to move their order from Full Supply to COU, they will need to receive an initial supply first and apply the COU file to that initial supply. The COU should not be applied to a Full Supply order.
When an order for Full Supply is placed, the product will contain all features for the customer’s area of interest. When a product refresh is ordered, for this type of order, the supply will contain all the features for the area of interest which will include features that have not changed. This supply mechanism will not explicitly identify which features are new, have been modified or have been removed. This can still be identified by querying the reasonForChange and the beginLifespanVersion attribute.
When an order is placed for COU the first order received will be an initial supply. Initial supply refers to the first order that a customer takes of OS MasterMap Highways Network under the COU order type. An initial supply contains all features for the complete area covered by the order, and every feature will be an “insert”. Updates, which contain the latest changes to the features are automatically sent out.
Following the initial order, a COU will be supplied, at the selected update schedule of the customer. COU only contains new features, new versions of features and information about deleted features. A feature can be deleted from the customers holdings for two reasons; the feature has been deleted and the id will no longer exist in the product, or the feature has moved outside of the customers area of interest but still exists in the national product and therefore could be reinstated in a customer’s holdings. To identify the difference between the two deletes the reasonForChange can be used. If the value is “end of life” then this feature has been permanently deleted whilst any other change value would indicate the feature has moved outside of the holdings and could be reinstated in future. Any feature within the area of interest that has not undergone any change will not be supplied.
The features within the initial supply and COU are provided as transactions. A transaction identifies if the feature is new, modified or removed from the product. The three types of transactions are:
<os:insert>
These are features which have been newly inserted into the product or the customer’s area of interest since the last product supply.
<os:replace>
These are features which have had either a geometry change or an attribute change since the last product supply. The whole feature will be supplied, not just the changed attributes. The recommended action would be to completely replace the feature which currently exists in the customer’s holdings.
<os:delete>
These are features which have ceased to exist in the last product release or have moved out of the customer’s area of interest. Features which have been deleted will be supplied with the entire feature’s attribution. These features should be removed from the customer’s live data holding.
The initial supply will contain an insert transaction for all features in the customer’s holdings. The following COU supplies will have insert and replace transactions in one GML file and deleted features will be supplied in a separate file. Where a delete file has been supplied, this must be loaded before the file containing inserted and replaced features. There are examples in on the GML examples page of the different types of transactions.
OS MasterMap Highways Network – Roads is supplied in three formats: Geography Markup Language (GML 3.2.1), GeoPackage and vector tiles. All formats are compressed into a regular zip file (.zip).
The Road Network is a topologically structured link and node network made up of the following feature types:
| Feature type | Description |
|---|---|
OS MasterMap Highways Network has been built with the INSPIRE Transport Networks Data Specification as a basis. This has been extended to include the additional properties required by BS 7666-1:2006, defined within the NSG to ensure that conformance to both INSPIRE and BS7666-1:2006 can be achieved.
Each feature within the OS MasterMap Highways Network will have the following common attribution:
gml:id, gml:identifier and inspireId
beginLifespanVersion
inNetwork – this shall always be set to “OSHighwayNetwork”
reasonForChange
validFrom
This is assigned a nilReason value “unknown” for most features.
In addition, many of the attributes which have been inherited from the INSPIRE Transport Network model have a stereotype of ‘voidable’, for example “beginLifespanVersion”. Where these attributes have not been populated there is a requirement to give a reason for this. This will be specified in the GML through an attribute called “nilReason”.
This section describes the features which make up OS MasterMap Highways Network - Roads. The attributes associated with these feature types are listed below along with a brief description of their data properties.

OS MasterMap Highways Network – Roads is a relational product. This results in there being relationships between different feature types.
The table below identifies how the feature types relate to one another, and which attributes are the primary and foreign keys. This is also represented in the image below. The attribute at the arrowhead is the primary key and the attribute at the base of the arrow is the foreign key.

This technical specification provides detailed technical information about OS MasterMap Highways Network – Roads. It is targeted at technical users and software developers.
The OS MasterMap Highways Network is the authoritative highway network for Great Britain. It brings together Ordnance Survey’s large-scale road content, the National Street Gazetteer (NSG), the Trunk Road Street Gazetteer (TRSG) and the Scottish Street Gazetteer (SSG).
OS MasterMap Highways Network is made up of four product schemas: Linear Highway Network, Highways Dedication, Routing and Asset Management Information and Highways Water Transport Network. These four schemas create three products which are a part of the OS MasterMap Highways Network family:
OS MasterMap Highways Network – Roads
OS MasterMap Highways Network – Routing and Asset Management Information
OS MasterMap Highways Network – Paths
This technical specification will cover the OS MasterMap Highways Network – Roads (from here referred to as Road Network) product.
All features that comprise the OS MasterMap Highways Network – Roads will be assigned a persistent identifier, which in most instances is an Ordnance Survey TOID (Topographic Identifier). For features which have originated from the National Street Gazetteer or Scottish Street Gazetteer, the persistent identifier will be either a Unique Street Reference Number (USRN) for Street features or a unique ID for Maintenance, Reinstatement, and Special Designation.
Identifiers shall be encoded in three properties in the data:
gml:id – this is a feature identifier comprising the shorthand prefix namespace and local identifier used to uniquely identify and reference the feature within the dataset. Example: osgb4000000009461245.
inspireID – this is a complex property made up of a localId, namespace and versionId which uniquely identifies the feature and version within an INSPIRE dataset. The versionId will not be populated in the OS MasterMap Highways Network products.
An example of a full identifier is given below:
Where features have come from the same source as the OS MasterMap ITN Layer, the identifier will be persistent and correspond to the same feature in ITN.
The gml:id is used throughout the OS MasterMap Highways Network products as the identifier used to reference to other features.
TOIDs (Topographic Identifiers) are strings of up to twenty characters which consist of two parts:
Local identifier: 16-digit numeric string (0-9)
gml:id – ‘osgb4000000009461245’
localId – ‘4000000009461245’
USRNs (Unique Street Reference Numbers) are strings of up to twelve characters which consist of two parts:
Local identifier: Up to an 8-digit numeric string (0-9)
gml:id – ‘usrn82101225’
localId – ‘82101225’
Although the gml:id is the identifier used for referencing features in OS MasterMap Highways Network products, the localId is the identifier used by the National Street Gazetteer, National Land and Property Gazetteer and the OS AddressBase family of products.
Unique IDs for Maintenance, Reinstatement, Special Designation are strings of up to 17 characters which consist of two parts:
Local identifier: 14 alphanumeric string
The ID for HighwayDedication is a string of up to 25 characters comprised of the characters “esu” followed by three parts separated by “_”:
LHA authority code
ESU it references
dedication code in the NSG
For example, esu4720_4280330430163_8, esu4720_4280340431456_11
gml:id – ‘id_3700MA01862142’ or ‘esu4720_4280330430163_8’
localId – ‘3700MA01862142’ or ‘esu4720_4280330430163_8’
identifier - ‘http://data.os.uk/3700MA01862142’ or ‘https://data.os.uk/id/ esu4720_4280330430163_8’
OS MasterMap Highways Network– Roads and OS MasterMap Highways Network – Paths will be supplied in three formats: Geography Markup Language (GML 3.2.1), GeoPackage and vector tiles. All formats are compressed into a regular zip file (.zip).
OS MasterMap Highways Network– RAMI will be supplied in two formats: Geography Markup Language (GML 3.2.1) and GeoPackage. All formats are compressed into a regular zip file (.zip).
OS MasterMap Highways Network extends the INSPIRE Transport Networks (Road and Water) Technical Specification (version 3.2).
OS MasterMap Generic Network model extends the INSPIRE Base Models - Generic Network Model (version 3.0rc3).
OS MasterMap Highways Network extends the INSPIRE specification to include the additional properties required by BS 7666-1:2006 defined within the National Street Gazetteer (NSG) Data Transfer Format (DTF) and Scottish DTF (SDTF) to ensure that conformance to both INSPIRE and BS7666-1:2006 can be achieved.
The data structure is described by means of UML class diagrams and accompanying data dictionary tables. The specification conforms to the rules for application schema specified in ISO 19103 Conceptual schema language and ISO 19109 Rules for application schema, as adopted by INSPIRE.
Colour conventions have been used in the diagrams and tables to allow users to easily distinguish the INSPIRE feature classes (coloured grey) from the Ordnance Survey feature classes which extend the INSPIRE specifications (coloured orange). All code list classes are coloured blue, enumeration classes are green and data types/union classes are purple.
The data dictionary tables use orange for a feature type, blue for a code list, green for enumerations, and purple for data types.
Class names are conceptually meaningful names (singular noun) in UpperCamelCase.
Class names end in “Value” where the class is assigned the stereotype <<CodeList>> or <<Enumeration>>.
Class names shall end in “Type” where the class is assigned the stereotype <<DataType>>.
Property names (attributes and associations) are in lowerCamelCase.
The following stereotypes are used on UML elements:
Constraints are defined on the Class using human readable language only. Constraints are displayed on the class diagram included below. These constraints are used to define co-constraints or restrict INSPIRE properties only.
There are three key types of relationship defined between classes:
Generalisation/Specialisation – Used to denote either:
An extension relationship. The target class represents the same real-world entity and is extending it to include additional properties not defined on the parent class.
A sub-typing relationship – The target class defines a specialised sub-type of parent feature. For example, TransportNode is a specialised sub-type of a generic Node class.
This class has the same name as the class it is extending.
Directed Association – Used to denote relationships between features. These relationships are encoded as references to the related feature via the identifier assigned in the gml:id. The directed end shall be assigned a name which describes the relationship between the two features and a multiplicity.
Aggregation – Used to denote part-of relationships. Aggregations are used to describe loose part-of relationships. If the parent feature ceases to exist, then the part feature can continue to exist. For example, a Road Name may cease to exist, but the Road will still exist.
This technical specification includes the following sections:
gml:identifier – this is a global feature identifier and can be used to identify and reference the feature within other datasets. Example:
Namespace: This is either a HTTP URI, () or shorthand prefix (‘osgb’)
identifier - ‘’
Namespace: This is either a HTTP URI () or shorthand prefix (‘usrn’)
identifier -
Namespace: This is either a HTTP URI () or shorthand prefix (‘id_’)
| Stereotype | UML Element | Description |
|---|
<<ApplicationSchema>> | Package | Parent package containing sub-packages and elements that comprise part of the modular specification. |
<<FeatureType>> | Class | A spatial object type. [ISO 19136]. |
<<Type>> | Class | A structured data type with identity. |
<<DataType>> | Class | A structured data type without identity. [ISO/TS 19103]. |
<<Union>> | Class | A structured data type without identity where exactly one of the properties of the type is present in any instance. |
<<Enumeration>> | Class | A fixed controlled set of values for a free text data type. |
<<CodeList>> | Class | A controlled set of values for a free text data type that may be extended. |
<<Voidable>> | Property | A property that is required but is either not currently captured (unknown) or is partially populated (unpopulated). |
<<LifecycleInfo>> | Property | Property considered part of the life cycle information. |

A RoadLink is a linear spatial object that defines the geometry and connectivity of a road network between two points in the network. Road links can represent single carriageways, dual carriageways, slip roads, roundabouts and indicative trajectories across traffic squares. RoadLinks will be split for connectivity purposes (for example at junctions) and RoadNodes will connect the RoadLinks together. Each RoadLink will provide a reference to the RoadNodes at the start and end of the RoadLink.
RoadLinks will split where two links cross over or under one another when there is no connectivity, for example at bridges and flyovers. Therefore, the attributes “startGradeSeparation” and “endGradeSeparation” have been populated on the RoadLink. The Grade Separation attribute will indicate where there is or is not a physical connection between the roads in the real world. Grade Separation will determine if a RoadLink is above another; if the two RoadLinks, when referencing the same RoadNode, have different values then it is not possible to move between them at that point.
Where a RoadLink crosses a PathLink at a different level, both the RoadLink and PathLink will split. The attributes “startGradeSeparation” and “endGradeSeparation” will be populated on the RoadLink and PathLink. The Grade Separation attribute will indicate where there is or is not a physical connection between the road and path in the real world. Where the two links cross, the Road Node and Path Node will have the same identifier. Grade Separation will determine if one link is above another. If the two links, when referencing a Road Node and Path Node with the same TOID, have different grade separation values then it is not possible to move between them at that point.
The context diagram shows how the RoadLink has been inherited from INSPIRE and the attribution held on the RoadLink.

A Road feature is a link set which represents a collection of RoadLink features used primarily by motorised vehicles that share the same name (e.g. Bilston Road) or classification number (e.g. A41). A Road will reference the complete collection of RoadLink features irrespective of which authority boundary it falls within. The feature will include Motorways, A Roads, B Roads and Named Thoroughfares (roads), as illustrated above.
The link set may not be contiguous across junctions or where a classified road consists of separate sections, which may be separated by some considerable distance. In addition, the same RoadLink feature may be referenced by multiple Road features.
The context diagram shows how the Road has been inherited from INSPIRE and the attribution held on the Road.
A compound feature that represents a road with a name or number. This may be a classified road, such as the A38, or a named road such as Romsey Road. This references a collection of RoadLinks.

A Street feature is the definition of the street as defined in the National or Scottish Street Gazetteer. A Street includes aggregated geometry. Where possible, the geometry of streets captured by a Roads or Highway Authority is spatially matched to the geometry of OS RoadLinks.
If any of the Street’s Elementary Street Unit(s) (ESUs) have been matched to a RoadLink(s) then the aggregated geometry of the RoadLink(s) will be provided.
If none of the Street’s ESUs have been matched to a RoadLink then the aggregated geometry of the ESUs will be provided.
The provenance of this geometry can be identified through the “geometryProvenance” attribute. They will represent either the complete Street or a section of a Street within an Administrative Unit, Town, or Locality and provides additional information about who is responsible for its naming and or numbering. A RoadLink can be referenced by multiple Street features.
The Street extends the Road to provide the additional attribution required to adhere to BS 7666:
USRN: The Unique Street Reference Number is the unique and persistent identifier of a Street assigned by the Roads or Highway Authority.
Street Type: The type of Gazetteer record for which the USRN relates. It is mandatory for all USRNs to be assigned a Street Type.
Operational State: indicates whether the Street is proposed, under construction, open, or closed (permanently or temporarily).
Responsible Authority: reference to the authority who performs an administrative function – notably naming and numbering.
A Street will split when it crosses the boundary of an Administrative Area where the local maintenance responsibility changes. A Street could also split at a town or locality boundary to allow properties to be located uniquely upon a street via a unique identifier (i.e. USRN).
In the definitions below, users should read the term Highways as Roads when applied to streets in Scotland.
Any road, footway, path, cycletrack, track or passageway that forms a highway. A highway represents individual subsections of Road which are managed (naming/numbering) by a specified responsible authority.
Constraints: A Street shall have at least one of designatedName (Type 1), descriptor (Type 2), nationalRoadCode (Type 3), localRoadCode (Type 3), or localName (Type 4). If a Street has a descriptor, it shall not have a designatedName. If geometryProvenance does not = "Ordnance Survey" then 'link' shall be null. If the roadClassification = "Motorway" or "A Road" or "B Road" then the nationalRoadCode shall not be null.

OS MasterMap Highways Network – Roads is supplied as one GeoPackage file for GB. GeoPackage (*.gpkg) is an open, standards-based data format, as is defined by the Open Geospatial Consortium (OGC). It is designed to be a lightweight format that can contain large amounts of varied and complex data in a single, easy to distribute and ready to use file.
GeoPackage can be used in most GIS software in its native format without translation. GeoPackage attribute names are not limited in length. A GeoPackage file has no size limit, and it supports raster, vector and database formats, making it a highly versatile solution.
The naming of attributes between GeoPackage and the Geography Markup Language (GML) file is very similar as GeoPackage files are not limited in the number of characters for an attribute name. The tables listed in this section map the GML attribute name to the attribute name in the GeoPackage files.
The GML contains an attribute which describes the geometry of the feature; this is not applicable for a GeoPackage file as they are separated by their geometry. Please note not all GML attributes have been mapped to Geopackage. In the GeoPackage attribute tables, a greyed-out box with an asterisk (*) marks a GeoPackage attribute that is not mapped from a GML attribute.
Entry
The junction facilitates entry onto the adjoining link.
Exit
The junction facilitates exit from the link.
The “CycleFacilityType” data type is attributed with a “cycleFacility” property with the data type of “CycleFacilityValue”. The following table describes the codes used to populate this field.
This value is provided from the National Street Gazetteer. Currently only “Unknown Type Of Cycle Route Along Road” is available for population. The other values are for future use.
| GML attribute name | GeoPackage attribute name |

OSMM Highways Network – Roads is supplied as a national vector tiles set in a single MBTiles file. This is a lightweight set of tiles that are efficient and fast to render in your software, and which provide high-resolution data and give a seamless experience when zooming in and out. The data is supplied in Web Mercator projection (ESPG:3857).
The naming of attributes between vector tiles and the Geography Markup Language (GML) file is very similar as the vector tiles set within the MBTiles file is not limited in the number of characters for an attribute name. The tables listed in this section map the GML attribute name to the attribute name in the vector tiles. Please note not all GML attributes have been mapped to vector tile attributes.
The vector tiles schema is detailed in the following tables. In the zoom levels columns within the table, the letter N indicates that the specified layer and attribute are not mapped within that zoom level, whereas the letter Y indicates that the specified layer and attribute are mapped within that zoom level.
| Layer | Attribute | Zoom level 0 to 13 | Zoom level 14 | Zoom level 15 |

This section describes how OS MasterMap Highways Network is defined in GML. An understanding of XML (Extensible Mark-up Language) and XML schema is required.
GML is an XML grammar for expressing geographic features. GML serves as a modelling language for geographic systems as well as an open interchange format for geographic transactions on the Internet. More information can be found on the Open Geospatial Consortium (OGC).
The XML specifications that GML is based on are available from the World Wide Web Consortium (W3C):
Information about Unicode and UTF-8, the character encoding we have chosen, is available on the Unicode Consortium website:
XML schemas are used to define and validate the format and content of GML. The GML 3.2 specification provides a set of schemas that define the GML feature constructs and geometric types. These are designed to be used as a basis for building application-specific schemas, which define the data content.
The Road Network uses the following application schemas; LinearHighwayNetwork.xsd, HighwaysWaterTransportNetwork.xsd and OSProducts.xsd which are referenced by the data. The LinearHighwaysNetwork.xsd defines the features which make up the Road Network. Therefore, it imports the INSPIRE transport network road application schema. The HighwaysWaterTransportNetwork.xsd defines the features which make up the Ferry Network. Therefore, it imports the INSPIRE transport network water application schema. Through the INSPIRE schemas both the LinearHighwayNetwork.xsd and HighwaysWaterTransportNetwork.xsd import the GML 3.2 schemas. These in turn import schemas produced by the W3C, which are available from the W3C website at The OSProducts.xsd defines the feature collection and feature members. In addition, this application schema will define the transactions used for a Change Only Update supply.
The Linear Highway Network schema document defines the namespace,
this is defined in the XSD at:
The Highways Water Transport Network schema document defines the namespace,
this is defined in the XSD at:
The application schema uses the following XML namespaces and their associated definitions:
