A great article on 3D mash-ups has appeared in the latest issue of New Scientist. The article includes quotes from the Ordnance Survey head of research, the people at the Digital Urban blog and people behind the Infoterra Skape project.
The article focuses on the potential of 3D mapping, with Bournemouth in southern England claimed to be the best mapped place on the planet since lasers were fired at the town from the ground and from the air to capture the height of buildings, trees and other features. This has resulted in a map accurate to 4 centimetres in x, y and z. By comparison 3D structures in Google Earth are accurate to about 15 metres...
A must-read for anyone into 3D urban modelling, the article can be found at; http://www.newscientist.com/article/mg20427366.400-3d-mashup-maps-let-you-edit-the-world.html
