Consultation on the National Street Gazetteer, GeoPlace DEC-Streets Consultation Version 4.0

GeoPlace wish to receive comments on the above consultation document.  Details of where to find and how to comment on the consultation document can be found in section 6 below.  The consultation will run from Tuesday 2 January 2018 to Wednesday 28 February 2018.


1. Introduction

The National Street Gazetteer (NSG) is the nationally definitive Street dataset, containing unique Street references (USRNs) linked to the names, additional street data (ASD) and extents of Streets in England and Wales for streetworks.  The purpose of the GeoPlace DEC-Streets, Reference Manual, is to:

•      Provide the source reference for GeoPlace to receive Street Updates from Local Street Gazetteers (LSGs) created and maintained by local government and ASD Updates from National/Regional Highway Authorities, in England and Wales.

•      Provide the basis for forming a consistent national dataset, the NSG, made up from the constituent LSGs and ASD, for NSG Users' and for the Ordnance Survey street products.

•      Strengthen the links between the Local Highway Authority Street Custodian and all other streetworks organisations and NSG Users'.

•      Ensure that accurate and consistent geospatial based street information is captured in LSGs and ASD is delivered as Street Updates and ASD Updates respectively, to GeoPlace.

•      Consider the technical definition of LSG, ASD and NSG data contained within the statutory legislation, supporting codes of practice and technical specifications specified in the documents.

•      Be used in conjunction with the release of the EToN v6 Technical Specification which became effective on 1st October 2013 and the 4th edition Code of Practice for the Co-ordination of Street Works and Works for Road Purposes and Related Matters dated October 2012.


2. Consultation

This consultation is on the revised version of the NSG GeoPlace DEC-Streets consultation version 4.0, in which there has been a comprehensive rearrangement of the sections making the order more logical and accessible.  These changes were made to accommodate the introduction of DTF8.1 v2.10 and to align it to the structure of the GeoPlace DEC-Addresses v3.4. Note that there is an aspiration to combine the two documents at a later date. Comments on all sections of the consultation document are invited from all consultees listed in consultation question 1, section 6, below. 

Sections 1, 2, 4, 5, 6, 8, 9.2 (including Appendix D) and 10 are considered to be common to both documents (DEC-Streets v4.0 and DEC-Addresses v3.4) and specific comments are invited from Authority Address Custodians and Street Naming and Numbering officers on these sections. 

The consultation will run from Tuesday 2 January 2018 to Wednesday 28 February 2018.


3. Content

Comments are invited about the structure of the new document and whether any further improvements can be made to all sections and appendices.

Sections 7 to 9, 16 and 18 and Appendices D and G have been previously consulted upon over the last two years and comments are not invited on the content or policy contained within these sections.

It is intended to revisit Sections 8 and 18 (Public Rights of Way) when Defra publishes the secondary legislation regarding the 2026 cut-off date.  At this stage it is likely that these sections will then be put out to a wider consultation across the PRoW community.

Section 19 (ASD Coordinate record).  Comments are invited on the content of this section.  It has not been possible to produce guidance because of limitations to DTF8.1 v2.10 in the following areas:

  • The creation of whole road ASD Coordinate records for Interest and Reinstatement records is not possible

  • A one-to-many relation between polygons and USRNs cannot be created.

Comments made should bear these limitations in mind.  When DTF8.1 is reviewed, this section will be revised.


4. Spelling and typographical errors

For all Authority Custodians and other DCA members please report spelling, punctuation, grammatical errors and other typos to the following thread on the Khub here which has been set up for this purpose.  This will help eliminate multiple reporting of the same error and make the correcting of the GeoPlace DEC-Streets easier.


5. Examples

More examples in the GeoPlace DEC-Streets are required.  If you have examples of best practice from within your organisation which illustrate points mentioned in the GeoPlace DEC-Streets, please submit them for inclusion in future versions of the document.

The consultation will run from Tuesday 2 January 2018 to Wednesday 28 February 2018.
