English NSG
W.D.M. Limited National Street Gazetteer (NSG) allows users to maintain and edit the Gazetteer while following the NSG 8.1 Data Transfer Format. In England and Wales, Local Street Gazetteers (LSG) are created and maintained by Local Authorities. They cover all streets in the Authority’s geographic area, regardless of maintenance responsibility. WDM®’s NSG can export out the required data in a wide range of formats.
NSG operates within WDM®’s Highway Integrated Asset Management System (HIAMS) while providing validation with GeoPlace, the definitive source of official address information that conforms to the British Standard and national Conventions.
The NSG allows user to manipulate the map to the precise location required, based on the street descriptor, ESU and locality etc or by record start and end dates.
Incorrectly placed ESUs can be removed from a street and added to another street. ESUs can be split and closed off from the original, using tools within the NSG.
Layers & Validation
Within the mapping software, a range of layers can be set up which can be used to help break down data into an easy-to-read format. These layers can be used to colour code ESUs, asset types (such as road type) and owner types – as the data changes so do the layers. Support for imported layers to show alongside NSG data in the map is included, for example, parish, district, and authority polygons.
NSG supports the adding and editing of polygons for ASD data. These shapes can be snapped to existing geometry on the map. Once the individual record has been saved, it is validated using the NSG 8.1 Data Transfer Format created by Geoplace.
WDM®’s NSG allows for the flexibility to include additional ESU/Street attribute fields to store more network information.
Web Query Builder (WQB)
Web Query Builder (WQB) is the NSG ad-hoc query tool enabling users or administrators to create their own reports and datasets from the data. This is a very flexible intuitive tool giving access to any published table or view and allowing filtering of data.
Security
The NSG security tool SecMan ensures users only have access to the NSG data they can view. This is controlled through rights given by the organisation's system administrators, for example, a contractor accessing the system can be set up to view and not edit data.
Crystal Reports
The ability to generate crystal reports showing mapping (in multiple formats) for viewing is available as an additional add-on. Along with the option of a dedicated GeoServer for outputting WFS layers, as a feed for use in third-party GIS software.
