This data represents LiDAR-derived intensity images (QL1) for Ashland County, Wisconsin in 2019 (QL1 - high resolution data with 8 points per square meter). LiDAR intensity is recorded as the return strength of a laser beam. It is a bi-product, provided as an integer number between 1-256. This number varies with the composition of the surface object reflecting the laser beam. A low number indicates low reflectivity while a high number indicates high reflectivity. The intensity of the laser beam return can also be affected by the angle of arrival (scan angle), range, surface composition, roughness, and moisture content.
