Contour dataset represents the earth's surface with all vegetation and man-made structures removed representing just the physical ground surface. Features represent approximated elevations. DEM used to derived / generate contours is based on re-classified (enhanced) Bare Earth DEM (1' resolution). The 2014 Reclassified LiDAR data was used to derive the Bare Earth DEM.
