In April 2009, Intelligent Addressing, the National Custodian of the NSG, published this streets information dataset in DTF7.1 format to be compliant with the British Standard for the representation of a street. Since then, Intelligent Addressing has run a dual hub, with the data in its original NSG-CSV format as well as the new format, in order to allow users to migrate from the old to the new format. As of April 2010, the NSG will only be published in the DTF7.1 data format.
The DTF 7.1 format offers a number of advantages over the old format;
- it is compliant with BS 7666:2006, the latest format of the National Standard âSpatial datasets for geographic referencing'
- it allows the incorporation of Additional Street Data such as height, width and weight restrictions, and one way exemptions
- it includes direction of travel information
- incorporation of dual languages in support of the Welsh Language Act.
Updated versions of the NSG are published on the 2nd working day of each month. The new service that Intelligent Addressing will provide gives clients access to the converted data on a dedicated ftp site on the day that the NSG is published. This means that there will be no interruption in supply to organisations that depend on this vital dataset for streetworks information.

01 April 2010
IA offers new conversation service for NSG users
Intelligent Addressing has developed a new conversion service for users of the National Street Gazetteer (NSG) who are unable to import the latest format of the NSG, which from 5th April 2010 will be published in DTF7.1 data format.
What does DTF 7.1 offer over NSG CSV?
- BS7666:2006 compliancy
- 2 new data records (Type 64 â Height Width and Weight, one way exemptions)
- Direction of travel information
- Support of the Welsh language act
Who is it aimed at?
Anyone who takes NSG data that has not been able to move to DTF 7.1 (in the main this will be utilities and local authorities)
What software does the customer need to utilise it?
No additional software. The service has been devised to accommodate those organisations which don't have appropriate software in place to accommodate the DTF 7.1 format.
How is the service delivered and how quickly?
The user will access the data from an ftp site which will be created for them. Data will be made available here when the data is published - i.e. the 2nd working day of each month provided that a Purchase Order is sent to the NSG helpdesk before hand
What's the cost?
Â£495+vat per month. This is a flat fee which gives users access to all 174 contributing authorities.
