UK – A new national street database providing details of low bridges, narrow roads and other restrictions could help to reduce satellite navigation errors. The National Street Gazetteer (NSG) lists over one million UK streets and is already widely used to help coordinate road works across England and Wales. It has been updated to a new format that enables highway authorities to record heights, weights and width restrictions and directions against individual roads and streets.
The new DTF 7.1 format, which is compliant with BS7666:2006, also enables closer alignment with the National Land and Property Gazetteer, the country’s definitive list of property addresses. Improving both the richness of the data held in the NSG and the data checking routines will enable those involved in road works to consult and coordinate more effectively, reducing inconvenience and congestion.
Significantly the ability to record heights, weights, width restrictions relating to weak bridges, low bridges or simply streets not wide enough for HGVs, now makes the NSG particularly useful to emergency services, transport firms and satellite navigation companies.
