This 3-foot resolution hillshade depicts shaded relief based on the Digital Terrain Model. Hillshades are useful for visual reference when mapping features such as roads and drainages and for visualizing physical geography. The hillshade represents the state of the landscape when countywide LiDAR data was collected in 2018 and 2020. A full product datasheet is available at: https://vegmap.press/sc_hillshade_datasheet
