BBC News July 19th … archaeologists intend to ‘virtually’ excavate Stonehenge and its surrounding environs in a mult-million poun mapping of the terrain and what may lie bured under the ground – with pinpoint accuracy. Millions of measurements will be taken and will then be incorporated into ‘gaming’ technology to produce 2D and 3D images. Equipment will explore over 14km within the next 3 years, led by Vince Gaffney of the University of Birmingham. Large banks of sensors will be pulled by a quad bike and GPS will the plot the measurements precisely. Sounds terrific.
