The Hillshade makes elevation data more legible to and more easily interpreted by the human eye.
The DEM is a County-wide relief map of ground elevation interpolated from LiDAR mass points. It provides visualization of the county's valley and ridge systems as well as high elevations areas. The data can be used to generate slope data, model and analyze stormwater runoff, and for other general planning purposes. This data may not be appropriate for site specific analysis.
