Google Earth’s lost city of Atlantis “removed” from the map?

By | February 8, 2012

After three years, Google Earth map has finally been updated to remove a gridlike pattern which sparked rumors that the underwater city of Atlantis had been found.

Before: Google gave users false hope in its 2009 mapping, which suggested the lost city of Atlantis had been found

The exciting ‘non-discovery’ was made in 2009 when eagle-eyed internet users spotted a large grid on the seafloor that looked strikingly like the fabled city. Google was quick to explain that the misrepresentation was caused by overlapping datasets, and Atlantis had not been found, but the map remained – until now.

This week, Google announced that to mark the third anniversary of Google Earth, it had released a major update that promises to give users a ‘clearer view’ of Earth’s subterranean landscape.The new update, known as bathymetry, is the product of Google’s collaboration with Scripps Institution of Oceanography, the National Oceanic and Atmospheric Administration (NOAA), the US Navy, NGA and GEBCO (along with contributions from a few other organizations) that promises Google’s ‘most accurate view of the seafloor to date.’

The original version of Google Ocean was a newly developed prototype map that had high resolution but also contained thousands of blunders related to the original archived ship data,’ said David Sandwell, a Scripps geophysicist, in a statement.

‘UCSD undergraduate students spent the past three years identifying and correcting the blunders as well as adding all the multibeam echosounder data archived at the National Geophysical Data Center in Boulder, Colorado.’

The newest version of Google Earth includes more accurate imagery in several key areas of ocean using data collected by research cruises over the past three years.

The Google map now matches the map used in the research community, which makes the Google Earth program much more useful as a tool for planning cruises to uncharted areas,” Sandwell added. …

The lines are still there. Here is an animation I created with Simon Brown’s plug-in for the Paint.Net image editor (a nice free alternative to Photoshop).   The images are different sizes, contrasts and rotations, but you can still see that once they are (very crudely) overlapped that some, if not all, of the lines show real structures on the sea floor.
