Thanks to Tony Cagle's blog for the link to this PDF which describes how combining modern technology, geology and history has cast new light on the spatial distribution of tombs in the Theban Necropolis. The heart of the project is satellite imaging, which provides information not only about known structures, but about architectural features beneath the surface. At the moment the project is focusing on Sheikh Abd el-Qurna hill, where private tombs of noblemen are found, and has recorded over 500 tombs in its database, which can be accessed at www.cofc.edu/olgis . Analysis of existing tombs is also being used to predict the location of lost tombs. A fascinating project for archaeology as a whole.
