About this episode
We have archives of films, newspapers, even seeds -- what if we could make one for the entire surface of the earth? Drawing on his experience mapping an ancient city in the Honduran jungle, archaeologist Chris Fisher makes the case for scanning the whole planet with LiDAR -- a technology that uses lasers shot from an airplane to map the ground -- in order to preserve our cultural and ecological heritage.
