So, how does this LiDAR thing works? It has a very unique style. Firstly, the radar is fixed on the airplane. Then the airplane flies over the objective location while the radar aims “laser pulses hundreds of thousands of times per second,” said  Thomas Garrison Ithaca College archeologist. “And every time one of those lasers hits a point of resistance, it stops and sends back a measurement to the plane.”
