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. This talk was filmed at TEDxMileHigh. All TEDx events are organized independently by volunteers in the spirit of TED's mission of ideas worth spreading.
