GeoPlace Enhances NSG Services

Posted: 13 June 2013

GeoPlace has announced a number of enhancements to services available on the National Street Gazetteer (NSG) website.

This follows requests that have come from across the community of NSG data producers and consumers of that information.

The new functionality aims to further improve the data quality and allow more current data to be submitted and published for the NSG.

Under statute, each local highway authority in England and Wales is required to create and maintain its own Local Street Gazetteer (LSG) and Associated Street Data (ASD). These are then compiled into a master index - the NSG which is maintained by GeoPlace.

The NSG is a centralised unique referencing system, designed to improve the relationship between local authorities and utilities. Its fundamental aim is to make the street works process more efficient and reduce the impact of congestion on our roads.

GeoPlace maintains a number of services for both producers and users of the data, allowing producers to upload data on a monthly basis for users to download the areas required for their business operations.

Following the enhancements, local authorities will now be able to make a 'Second Submission' to the NSG hub within a calendar month. This will increase the amount of up-to-date data contained within the NSG.

The Highway Authorities and utilities Committee (HAUC) called for GeoPlace to alter the publishing mechanism so that utilities must upload an Operational District (OD) File before they can download NSG data. This will ensure that that all OD fields are kept up to date and stored centrally on the NSG website and ensure all works are carried out using the most up to date information.

Many local authorities operate Lane Rental Schemes which involve charging those carrying out works in the street for the time their works occupy the highway, with charges focused on the very busiest streets at the busiest times. The NSG is a facilitator of this scheme and will now enable local authorities to make available supporting documents in downloads of the data. Information from the Transport for London Lane Rental Scheme is included in the current and future NSG publications.

In addition, improved search facilities have been implemented on the NSG search site and general improvements have been made to validation speeds, both providing increased usability to users.



GeoPlace is a public sector limited liability partnership between the Local Government Association and Ordnance Survey. GeoPlace's role is to create and maintain the National Address Gazetteer and the National Street Gazetteer for England and Wales, providing definitive sources of publicly-owned spatial address and street data for Great Britain.
