Bringing Colour To Point Clouds

Until now, most commercially available airborne Lidar systems have operated on one single wavelength, reflecting energy from a pulse which is then used for classification or visualisation. New developments have produced the first multispectral Lidar systems, which scan using laser pulses in a number of different wavelengths. Multispectral Lidar data contains valuable information about the objects scanned. The fast-moving advancements in this field are likely to represent the next technological leap in Lidar systems.
