Product Updates

As part of our forward scoping, we are currently reviewing the use of the Open Roads Lookup Table CSV included in the OS MasterMap Highways data packages (available in the Resources folder).

We are particularly interested in understanding how the link between Highways and Open Roads is being used in practice, and how widespread its adoption is.

If you actively use the lookup CSV and are happy to share your use cases or provide feedback, we’d love to hear from you. Please get in touch with the Networks Product Team at [email protected].

Next release

The next release of OS MasterMap Highways Network is scheduled for August 2025.
