Resource provided by WisconsinView. This data represents a LiDAR-derived 1-m First Return Intensity Image for Rusk County, Wisconsin in 2020. This dataset has 1-m x 1-m grid cells and is in the WISCRS coordinate system for Rusk County: EPSG 9122. 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.
