of data that we're not sure what to do with, but when you zoom out, oh, there it is, clear as day.

The technology works a lot like radar, but it shoots laser pulses instead of radio waves to 3D

map a landscape. In 2016, it was used to map over 800 square miles of Guatemalan jungle,

including the area around the famous tourist site Tikal. Kanuta remembers when he and his colleagues
