Stirling Newberry writes "Nottingham University's Pavlopetri project spent months measuring a city that sank beneath the waves 3,000 years ago, perhaps in a tsunami. The result is a BBC documentary that features a detailed CGI reconstruction. 'The entire city – covering 20 acres – has been surveyed in ultra-high definition, with error margins of less than three centimeters. ... [T]he survey team has so far located scores of buildings, half a dozen major streets and even religious shrines and tombs.' eScience News chimes in about the oldest known submerged city, first inhabited 5,000 years ago and rediscovered in 1967. Of course, Slashdot readers will probably want to dig into the details of how stereo-vision mapping was used (PDF) to create the map in the first place."
