Resource provided by WisconsinView. This data represents a LiDAR-derived countywide hillshade image for Ashland County, Wisconsin in 2014. This dataset is in WTM coordinates, EPSG 3071 with elevation in meters. 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.
