This page details upcoming data that will be provided for the Crowd Sourced Name Point Feature Type in the OS NGD from the end of March 2025 to give you early insight. Data schema version 1.0 for this feature type is currently not available through the live access services. The information on this page is as accurate as possible, but is subject to change before launch.
A crowd sourced name collated from data submitted to the Vernacular Names Tool in the OS Data Hub, provided as a point feature.
The Vernacular Names Tool is a resource developed by Ordnance Survey to assist Emergency Services by incorporating user-submitted colloquial names for geographic features across Great Britain.
Crowd Sourced Names are unofficial names; for proper names and authoritative addresses, please see the unique identifiers available for each Crowd Sourced Name Point feature – the OSID, Matched UPRN, and Matched USRN.
The earliest date on which you can request a one-off snapshot of data in the past for data in this feature type is 27 March 2025.
The following sub-sections provide details about the attributes included with this feature type, their data types in the different output formats, and other important metadata about them.
Primary identifier for the feature. The OSID is a Globally Unique Identifier (GUID) and requires no centralised authority to ensure uniqueness. Note that the same OSID can occur in more than one feature type when a single feature is represented multiple times in the OS NGD.
