Address data for multiple geographic locations and flexible licensing options
Through Ambiental’s various partnerships with leading address data providers, we have the ability to provide address data for multiple geographic locations, with flexible licensing options. We can offer full UK address data coverage, and have the ability to provide address data for: Mainland Great Britain, Northern Ireland, the Republic of Ireland, the Channel Islands and the Isle of Man.
Ambiental can therefore provide the constituent address data licence components for all your address data requirements in the UK and Ireland. Coupled with our market leading automated data analytics and our unique approach to buffering/ building outlines, we are able to provide innovative and intuitive data on addressing and other perils information, all provided in a convenient way.
Great Britain
Great Britain benefits from the Ordnance Survey’s highly accurate AddressBase product which can supply more than 38 million live or historic addresses. Within AddressBase a unique property reference number (UPRN) is assigned to each property for its lifetime. This consistent point of reference ensures that the property can be identified even if the name or the address of the property has changed. Each property within AddressBase is also assigned a set of geographic coordinates, which allow the risks associated with the spatial location to be accounted for.
AddressBase can be licensed as one of three product variants, depending on the level of detail and information that you require: AddressBase, AddressBase Plus and AddressBase Premium. A summary of each product is outlined below:
