Resource provided by WisconsinView. This data represents a LiDAR-derived Digital Elevation Model (DEM) for Barron County, Wisconsin in 2005. 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.
