Promote your value to colleagues – Gazetteers @ GIS Day helps you to demonstrate the huge benefit of using geographic insights more widely.

Every local authority service uses location data to fulfil its remit. Address and Street data is the engine that drives your local authority’s capability, with UPRNs and USRNs being available to support the services for residents in just about every department.

As the LGA says “The Unique Property Reference Number – the unique identifier for every addressable location – is key to almost everything that’s delivered or achieved by councils.”

The people who make it happen

Each authority’s address assets are updated and maintained by Local Land and Property Gazetteer (LLPG) Custodians. Every highways authority has a Local Street Custodian (LSG) who’s responsible for that crucial street data, underpinning statutory roles like permitting. And the Street Naming and Number (SNN) Officers at the forefront of addressing processing applications for new and changes to addresses as well as channelling intelligence from a multitude of other sources to the Custodians, so the information is recorded quickly and accurately. Some SNN officers with direct access to LLPGs making those changes for immediate use to the benefit of all.

Find out more about the role of your Address and Street Custodians and Street Naming and Number Officer.

Gazetteers@GIS Day takes place on Wednesday 15th November.

Supporting public services, emergency response and business.
