Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment he has made of the accuracy of (a) spelling and (b) location of Welsh place names in the Ordnance Survey data.

Place names in Ordnance Survey data are sourced through updates received from authoritative bodies such as Local Authorities, or through ‘on the ground’ capture. To ensure that Ordnance Survey (OS) maps provide an accurate representation of the names in use in Wales in both their positioning and spelling, all data maintenance at Ordnance Survey is subjected to quality control as per ISO 19158 Geographic Information: Quality Assurance of data supply (2012) . This quality control methodology is itself scrutinised as part of a quality assurance process that is entirely separate from production.

In the case of potential naming errors being identified we would complete our investigations through consultation with acknowledged authorities such as Local Authorities or National Parks. Reporting errors can be made through the Ordnance Survey website: https://ordnancesurvey.co.uk/contact-us.
