This page aims to provide all the information to evaluate if the method of associating the respective identifiers is suitable for your needs. These identifier relationships have been extracted from existing premium products and are presented in a standalone table for easy and open access to the information. It describes which product the information was extracted from, what information was extracted and how the source product derived the original association between the identifiers.
This relationship is between the Topographic Identifier (TOID) of the RoadLink features and the TOID of Road features in OS MasterMap Highways Network.
A Road feature is a link set which represents a collection of RoadLink features that share the same name (e.g. Bilston Road) or classification number (e.g. A41). The relationship is extracted using the reference to the
RoadLinks which make up each Road feature in the ‘link’ attribute within OS MasterMap Highways Network – Roads product following its release.
The relationship is determined by the link reference within OS MasterMap Highways Network - Roads, demonstrating the RoadLinks of which the Road features are composed.
As this relationship is determined using a single source product the version information provided will always be the same as the version of the feature used to create the correlation.
A Confidence Value is assigned to indicate the reliability of the version information provided in this product in relation to the version of the features used to form the correlation in the original product. The Confidence Value is given for each relationship, which will always be defined in this relationship as:
| Confidence Value | Definition |
|---|---|
Version information is correct | The version information provided is the same as the version of the feature used to create the correlation. |
