“I got a laser return from the butt of Otis, one of the more famous brown bears up there,” Cusick said. “I thought, ‘Wow, this just might work.’”Lidar, which stands for “light detection and ranging,” emits beams of light to measure three-dimensional objects or areas. When light waves hit an object, they bounce off and return to the sensor. Computers then use the speed of light to calculate the distance between the sensor and all the points. That figure is then processed using software that can model a three-dimensional object. Scanners have become standard technology that is deployed from the ground, the sky and satellites to measure vegetation growth. Now, they’re being used to measure bears’ length, height and girth.
Insurance companies are probably going to start using LIDAR to measure their policy holders...
