The Ludwig Boltzmann Institute for Archeological Prospecting and Virtual Archeology, in Vienna. Their methodology page said they want to avoid “destruction by excavation.”
A National Geographic writer’s article in der Spiegel described how this Institute cooperated in a project to learn about, without fully uncovering, Bronze Age houses on the Greek island of Santorini that were buried by a massive eruption around 1600 B.C.E. The project partners laser-scanned the village from 850 positions. The University of Vienna did ground-penetrating radar measurements of unexcavated areas. A firm in Vienna helped process the data into artist’s renderings and presumably maps. German National Geographic called the renderings “photogrammetrically created 3D models.”
They found third floors.
