## Data issues

Please see the [OS MasterMap Highways Network Known Data Issues page](/os-downloads/products/transport-network-portfolio/os-mastermap-highways-network-fundamentals/os-mastermap-highways-network-known-data-issues.md) for details of live and resolved data issues for the products.

Due to differing publication schedules, OS MasterMap Highways customers who also use OS Open TOID or OS Open Linked Identifiers may notice some misalignment of identifiers between these products. This misalignment should be resolved in the next scheduled refresh of OS Open TOID / OS Open Linked Identifiers.

## 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 <networksproductteam@os.uk>.

## Next release

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