The British Geological Survey (BGS) has transferred masses of data onto a 3D map of Britain. The project aims to show how different types of rock make up the island’s geology. The BGS website explains how the model was devised, and features screensavers for visitors to download - a novel and fun way to fly around Britain without leaving your desk. The 3D model is an intelligent use of information technology that will amaze both novice and expert.
