This data represents a LiDAR-derived 60-cm Bare Earth DEM Hillshade Image for Marathon County, Wisconsin in 2021. This dataset is in the WTM coordinate system: EPSG 3071. Hillshading is a technique used to visualize terrain as shaded relief, illuminating it with a hypothetical light source. The illumination value for each raster cell is determined by its orientation to the light source, which is based on slope and aspect.
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.
