A piece of software has been released that allows public and private sector organisations, such as the emergency services and insurance firms, to search more than 813,000 postal and non-postal addresses in Northern Ireland.
They can quickly pinpoint buildings to within one metre of their location.
Quickaddress with Pointer was developed by QAS in collaboration with Ordnance Survey Northern Ireland (OSNI) and uses OSNI's Pointer Plus data, a comprehensive commercial address database.
Previously, public and private sector organisations such as the emergency services, utilities and insurance companies had to rely on the Royal Mail PAF database.
Stan Brown, acting chief executive of Ordnance Survey, said, "Quickaddress with Pointer is the first single database of all addressable properties for a UK region. Employing groundbreaking software, it stores more than 813,000 postal and non-postal addresses in Northern Ireland."
Harry Meikle, QAS group managing director, said, "The ability to pinpoint exact locations to the property level is critical for many types of organisations seeking to offer improved services."
He added that by using Quickaddress with Pointer, local government and utility companies, for example, can make service provisions more effectively, and insurance, financial or environmental firms can perform risk analysis based on accurate address data.
There are, however, no plans to produce similar software for other UK regions.
