NLPG & NSG Win Prestigious European Award

Posted: 11 December 2009

The National Land and Property Gazetteer (NLPG) and the National Street Gazetteer (NSG) have received a Best Practice Award at a European Spatial Data Infrastructure Conference.
Twelve finalists, including the NLPG/NSG managed to reach the last stage of the competition process, out of 130 original submissions from across Europe. All twelve finalists received the Award and the NLPG NSG were the only entries from England and Wales to do so.
In a nutshell a Spatial Data Infrastructure (SDI) provides the means for sharing information more effectively in order to deliver higher quality services to citizens. As the world becomes more complicated managing change and the problems that arise from it, such as pollution, security and climate change also requires better information for decision and policy making. Since everything happens somewhere an understanding of location and geography is vital.

The event, organised by e-SDI net plus on behalf of the European Union, attracted an international audience engaged in Spatial Data Infrastructures and related geospatial related activities at European, national, regional and local levels.

The two gazetteers have implemented the information management principles of collecting definitive data once, at source. This involves all the 348 local authorities for the NLPG and 172 for the NSG, who are continually improving the quality of the data. They are also providing regular updates to the two central data hubs from which the data can be accessed by any organisation needing the data to support the provision of services. It is the most successful initiative of its kind involving local government in England and Wales.

"We are delighted that the NLPG/NSG has won this award. It is further confirmation of the value of our data infrastructure model. The process uses standards and collects information on addresses and streets locally from source, and then compiles it centrally into an online national data hub. This process is both accurate and efficient" said Steve Brandwood, Programme Manager, LGIH. "The judges in particular noted the collaborative effort involved with the ten year long programme. They also noted the importance of the rigorous standards and legislative drivers behind the gazetteers," continued Brandwood.

Notes to Editors:

The NLPG was initiated in 1999 to become the master address dataset for England and Wales and the central hub for the 376 address creating Local Authorities and their Local Land and Property Gazetteers (LLPGs). Based on twelve digit unique property reference numbers (UPRNs) the underlying principle of these gazetteers is to provide a single definitive address database for all departments and systems across a local authority in order to cut costs, improve efficiency and service delivery. www.nlpg.org.uk

The NLPG is a joint venture between the Local Government Information House part of IDeA and Intelligent Addressing Limited.


Required under the New Roads and Street Works Act, the National Street Gazetteer (NSG) is a comprehensive list of over 1 million named and un-named streets, footpaths and thoroughfares, the definitive source for anyone with an interest in streets and their usage. There are over 300 organisations, utilities such as gas, water and electricity, BT, plus cable and communications companies, named as âStatutory Undertakers' approved by the Department of Transport to download this data, which conforms to the BS7666 Standard. The NSG is a government initiative to create an unambiguous referencing system, using Unique Street Reference Numbers (USRNs) with which to identify any length of highway or road in England and Wales. Set up initially to improve highway maintenance, under the New Roads and Street Works Act, the NSG enables Utility companies and local councils to coordinate and know where and when to dig their holes. Under legislation each highway authority is required to create and maintain its own local street gazetteer (LSG) and additional street data (ASD), which is then compiled into one master index, the NSG, for access by others via the NSG online hub. The NSG is run on behalf of local government by the Improvement and Development Agency (IDeA) with Intelligent Addressing (IA) as the national custodian.

Intelligent Addressing is a specialist private sector consultancy (an SME) employing recognised experts in addressing. It was originally set up to help develop the National Land and Property Gazetteer (NLPG) on behalf of local government and now manages the NLPG and NSG (National Street Gazetteer) central data hubs under the terms of the Mapping Services Agreement (MSA) with local government.

The Improvement and Development Agency (IDeA) works in partnership with all councils, to enhance the performance of the best, accelerate the speed of improvement of the rest, and develop the sector as a whole.

Working in partnership with the local government community developing national infrastructure projects that enable councils to deliver local services more effectively, LGIH acts as an intermediary between the public and the private sector enabling it to negotiate with private companies on behalf of local authorities in order to provide key parts of a technical infrastructure for improved service delivery.
