Info: This lidar data dataset was created by the WisconsinView Partners (WVP) – the WI Department of Administration’s Geographic Information Office in collaboration with the UW-Madison Space Science and Engineering Center’s (SSEC) WisconsinView repository. Original lidar data in tiled format from federal or local county/city lidar projects were used to create countywide mosaics of datasets such as DEMS, Intensity images, and DSMs in various projections and coordinate systems.

Title: LiDAR-Derived Countywide First Return Intensity Image for Marathon County, WI 2021
Description: This data represents a LiDAR-derived 2-ft First Return Intensity Image for Marathon County, Wisconsin in 2021. This dataset has 2-ft x 2-ft grid cells and is in the WISCRS coordinate system for Marathon County: EPSG 7618. 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.
