| 100 Foot Elevation Polygons (LiDAR-based) | Elevation polygons created from a three foot LiDAR DEM produced in 2008. The DEM is searchable under the Item Name DEM_LIDAR_PDX. | Land | 10/07/14 11:42 AM |
| 2 foot contours (LiDAR-derived) | 2' contours derived from 2004, 2005 and 2007 LiDAR data. All contours derived from bare-earth LiDAR point returns. The bare earth returns are a representation of the Earth's surface where all man-made structures and vegetation have been removed. | Land | 10/07/14 11:42 AM |
| Bare Earth DEM-Based Hillshade | DEM-based hillshade represents the earth's surface with all vegetation and man-made structures removed leaving bare points representing just the physical ground surface. The Hillshade is derived from the 2014 LiDAR Survey flown | Land | |
