linkreferenceconfidencevalue
This page details upcoming data that will be provided for the Link Reference Confidence Value Code List in the OS NGD from the end of September 2025 to give you early insight. Data schema version 2.0 for this code list is currently not available through the live access services. The information on this page is as accurate as possible, but is subject to change before launch.
This code list is used in association with the Link ID Confidence attribute which is present within the Bus Lane, Cycle Lane and Street Light Feature Types. The code list provides an indicator as to the confidence of the accuracy of the reference from the feature to its associated Road Link or Path Link.
V2.0 of the code list was released on 25 September 2025.
What's new?
Two new values have been added to this code list for v2.0:
Geometry Misalignment – A match has been made, although the angle of the geometry is greater than 50 degrees.
Network And Geometry Conflicts – A match has been made but there are multiple conflicting features to choose from, possibly at a junction, and the angle of the feature is greater than 50 degrees.
The new values have a 'new' emoji (🆕) against them.
Complex Network Features
There are multiple possible features in the match, possibly at a junction. The most logical links have been selected. This has a medium confidence.
Expected Data Output
A one-to-one match has been made between the feature and the network link. This has a high confidence.
🆕 Geometry Misalignment
A match has been made, although the angle of the geometry is greater than 50 degrees. This match is of lower confidence.
🆕 Network And Geometry Conflicts
A match has been made but there are multiple conflicting features to choose from, possibly at a junction, and the angle of the feature is greater than 50 degrees. The most logical link has been selected. This match is of lower confidence.
No Corresponding Match
There is no corresponding link within the tolerated distances.
