Wisconsin Department of Administration - Geographic Information OfficeThis data represents a LiDAR-derived 2-ft First Return Intensity Image for St. Croix County, Wisconsin in 2021. This dataset has 2-ft x 2-ft grid cells and is in the WISCRS coordinate system for St. Croix County: EPSG 7634. 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.GeoTIFFhttps://geodata.wisc.edu/catalog/8c752c8b-1fcb-476d-a126-647258a66376engWisconsinViewPublicElevationLiDAR-Derived Countywide First Return Intensity Image for St. Croix County, WI 2021DatasetsWisconsin2021University of Wisconsin-Madison
