Mapping the World’s Largest Caves
Scientists have begun mapping three giant catecaves in China using laser scanninglaser-scanning
technology. This expedition marks the first time anyone attempts to use this technology to
map underground caves. The technology is especially useful because it is difficult to see the
walls and ceilings in the large caves with traditional lights. For the scientists, the highlight
of the expedition is seeing images of 50-meter-tall stalagmites. Stalagmites are beautiful
columns that rise from the floor of the cave. Without the lasers, this would not have been
possibilitybeen possibile. Lasers can also be used for other things, such as medical procedures. Lasers
scanningLaser-scanning technology will help scientists to better understand caves for years to come.
