The Transport Network theme includes road, rail, air and water transport networks together with related infrastructure and links between different networks. The NSG is a national compilation of individual English and Welsh local authority street datasets representing a range of street network and related information such as street name and location details, street geometry and a range of Additional Street Data and falls squarely under the view and download requirements of INSPIRE.
GeoPlace has provided a Web Map Service (WMS) for viewing and a Web Feature Service (WFS) for downloading data. A user makes a request to view or download data via a web mapping service or GIS application. An image of the street network is served up allowing an overlay within the user's own data. Access to the service is via a secure login for registered NSG users only available at services.geoplace.co.uk/#Transport-Networks.
The central provision by GeoPlace of view and download web services removes the need for individual local authorities to publish data separately, providing the sector with substantial savings This is one of the first services in the UK to release data for the Transport theme and GeoPlace plans to expand the service with more queries in the future.
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.
National Street Gazetteer
The National Street Gazetteer (NSG) contains definitive information for streets in England and Wales and primarily allows local authorities to manage all street works carried out by themselves and by statutory undertakers in an efficient manner on their network.
The INSPIRE Directive 2007
INSPIRE establishes an infrastructure for spatial information in the European Union and it was transposed into UK law in December 2009. The aim is to facilitate better environmental policy across the EU. Member States must make available in a consistent format spatial datasets which come within the scope of the Directive and also create network services for accessing the datasets.
The INSPIRE Data Specification on Transport Networks is available at inspire.jrc.ec.europa.eu/documents/Data_Specifications/INSPIRE_DataSpecification_TN_v3.1.pdf
Data Co-operation Agreement
The Data Co-operation Agreement issued by GeoPlace to all District, County and Unitary councils in England and Wales, provides for a legally binding agreement between the parties to support the creation and maintenance of address and street information for England and Wales and address information for Scotland through separate agreements).
