- Can you use OS Open Roads for in-vehicle navigation systems?
No. For the route restriction information that your users would need, such as one-way systems, width and height restrictions, we recommend OS MasterMap ITN Layer.
- Can I download OS Open Roads data covering just my local area?
Yes, GML data is available in files covering 25km2 each. ESRI Shape files, the other format in which OS Open Roads is available, are only available in a national dataset download.
If you need a high-level view of the road network in Great Britain, OS Open Roads is for you – and it's completely free.
