Czech scientists have come up with a way to explore flooded cave systems without having to go into them. Their solution: create a three-dimensional map of the cave. A company called Geo-CZ developed a new tool that uses 3-D technology to map historical and archaeological areas. The Cave Administration of the Czech Republic demonstrated it earlier this month. Jiri Sindelar of Geo-CZ said, “The input data are not made by individual pictures, but videos. This makes the on-site mapping incredibly faster.” To produce the 3-D images, someone still needs to wear a wet suit, helmet and other equipment before going into the cave. That has to be done only once and only long enough to film it. This is helpful because most caves are underground and can be dark. In addition, caves can be seriously dangerous when they are flooded. Last year, 12 Thai schoolboys and their football coach were trapped in a flooded cave for 18 days before being rescued.
