When Google Earth made to look in the depths of oceans and see the terrain under the sea, some people found that there are some grid-like patterns in the sea floor. As the grids look much like the city streets, the people started calling these grids as the streets of the lost city of Atlantis.
On the other hand, Google reported that the gridlines were the result of overlaying data sets from the sonar data used to map the floor of the ocean. Google has worked hard to remove these gridlines from the ocean floor finishing the rumors of Atlantis.
The updates have not only improved the accuracy of ocean maps but it has also been reported that 15% of the images have been taken from the sonar soundings taken at a resolution of 1 km. Sonar method has been used by the oceanographers to map the seafloor. The earlier versions had 10% of the seafloor provided from sonar soundings with much of the data taken from satellite exploration.
“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,” David Sandwell, a Scripps geophysicist, said in a statement. “UCSD undergraduate students spent the past three years identifying and correcting the blunders.”
Google upgraded the application with new seafloor data from the Scripps Institution of Oceanography at the University of California, San Diego (UCSD), the National Oceanic and Atmospheric Administration (NOAA) and other groups.
