Resource provided by WisconsinView. This data represents a LiDAR-derived countywide 1-m bare earth hillshade image for Dodge County, Wisconsin in 2017. This dataset is in WTM coordinates (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.
