Cardiff’s new Wales Millennium Centre building now takes centre stage on the nation’s most detailed maps – even though it has not yet been officially opened.
Surveyors from national mapping agency Ordnance Survey have used their high-tech measuring equipment to ensure the unique shape of the finished Cardiff Bay building could be set out in fine detail in the most sophisticated computer mapping of the nation – OS MasterMap.
"This is one of the most impressive buildings I’ve ever surveyed," says surveyor Simon James, "the huge building has an uniquely shaped theatre roof; and the exterior of slate, glass and bronze coloured stainless steel really does fulfil the intention of reflecting the industrial and cultural heritage of Wales."
The surveyors used state-of-the-art theodolite ‘total stations’ with lasers to measure exact distances, coupled with hand-held pen computers on which the fine details of the building’s shape were recorded. They also locked on to signals from a network of space satellites in the Global Positioning System to ensure the building has been precisely mapped out in relationship to neighbouring developments.
This level of detail is far greater than people expect to find on a tourist or motoring map, but is absolutely essential for many businesses and public services that need extremely detailed mapping of the whole country on a day-to-day basis.
Across Britain, an average of 5,000 updates are made every day to OS MasterMap, from small property extensions to major prestigious new buildings like the new Millennium Centre. The results of the latest survey work can be made available to commercial customers very quickly indeed – sometimes as soon as the next day.
Such detailed mapping is used by organisations such as fire services to pinpoint the scenes of emergencies, solicitors dealing with the buying and selling of property, mobile phone companies to provide the public with location-finding services, and utility companies to track the routes of pipelines and cables.
The Centre's opening celebrations will take place over the weekend 26–28 November 2004, starting with an inaugural televised gala concert starring opera singer Bryn Terfel.
