The USB interface is used to communicate to the microprocessor and the power is directly provided by the 11. A lidar allows to collect precise distances to nearby objects by continuously scanning vehicle surroundings with a beam of laser light, and measuring how long it took the reflected pulses to travel back to sensor. High resolution digital elevation models and maps of maximum vegetation height derived from the LiDAR data are provided for each site. What if my data contains anomalously high/low points? This is a fairly common problem with LiDAR data. By choosing appropriate reflectivity levels, the data from the University of Wisconsin LIDAR have been used to derive unique 2-D and 3-D views of the Atmospheric Boundary Layer (ABL) structure, and the variations in that structure with time.
