Throughout the city of Nottingham, under modern day homes and businesses and the Nottingham Castle, there is a labyrinth of medieval tunnels, dungeons and cellars. Now, using laser technology, researchers are collecting 500,000 data points a second, measuring the size and scope of the caves at a pace that was not previously possible.
The result is a chance to create an archaeological record of the caves, and create a 3D model that visitors can explore on the Internet. The researchers are producing sweeping, color animated views of the caves that users can zoom in and out of and crawl through, just as they might in a real cave.
