An Indiana University Geology Drone is demonstrated using lidar to survey the topography in the nature reserve near Bloomington High School North during Dronepalooza 2019, Sunday, September 8, 2019. According to the NOAA website, "LIDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface characteristics."
