Maps revolutionised by 3D system

Bournemouth has become the first town to be mapped using a new technique.

A new way of producing maps with lasers to create three-dimensional images has been tested in Bournemouth.

Ordnance Survey has used the system to produce a detailed computerised map of the town centre.

The map is the result of a three-year trial and the agency says it could revolutionise the way maps are produced and used.

Every metre of the town was captured using land-based and aerial surveys with high-accuracy lasers.

The lasers, which use 700 million points of light, plot detail including terrain, vegetation and buildings. The road network and aerial imagery were added to complete the maps.

Glen Hart, head of research at Ordnance Survey, said: "Imagine the emergency services being able to accurately visualise the scene of an incident before arriving.

"They would have foreknowledge of points of access, be able to see any obstructions and know the size and shape of any buildings involved. This technology could have a genuine impact on people's lives."

He added: "Given the level of detail that we've achieved, I think Bournemouth can confidently lay claim to being the best mapped place on the planet."

The mapping agency says it will continue the trials while it perfects the technology but predicts three-dimensional mapping will be a reality within five years.
