Transport Scotland and Ordnance Survey (OS) have announced that the Improvement Service’s National Street Gazetteer will be the definitive source of data on primary road routes in Scotland.

The primary route network is highlighted in various way on mapping products and is shown in green on OS maps. This indicates that the road is a trunk road and is maintained by Transport Scotland.

The Improvement Service – the local government improvement organisation for the country – said this recognises that its digital twin of the road network is the most current and authoritative source of street network information available, reports ukauthority.com.

Information in the National Street Gazetteer is sourced from Scotland’s roads’ authorities, including all 32 local authorities and Transport Scotland’s operating companies, and goes through a validation process to ensure it is nationally consistent and geographically accurate.

This includes the road network and layout, who is responsible for maintaining each section of road and relevant surface materials used, along with any special features that are of interest to utility or telecommunications company operating on the road.

The source information is supplied by all local authorities via a daily data supply, and the digital information is then provided to Ordnance Survey for inclusion in the OS Highways product suite.

Dom Cuthbert, strategic development manager at Ordnance Survey, said: “Our longstanding partnership with the Improvement Service made this seamless development a natural step forward. The information held in the National Street Gazetteer is vital to our transport datasets, and is of the accuracy, quality and currency on which our customers and partners rely.”
