Timescanners: Digital Scanners Explain Historic Architecture's Engineering Mysteries

Thanks to state of the art mobile laser scanners, scientists can now document the greatest architecture in history, from The Pyramids to St. Paul's Cathedral, as digital models with pinpoint accuracy. The digital representations take you inside, around and through the buildings, which means researchers can study and analyze sites without being in the field. The technology is already proving its worth - watch the trailer above to see how Petra was constructed and more!
