Abstract 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.
Purpose For general mapping purposes.
Supplemental Information 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.  The original 2014 Lidar collected by
WSI/Quantum Spatial Co., for the Oregon Department of Geology and Mineral Industries (DOGAMI).
