Open-File Report O-09-08, Lidar Mosaic Imagery of the Columbia River Gorge, Multnomah Falls to Cascade Locks, Oregon
Using a new laser based terrain mapping program called lidar (light detection and ranging), the Oregon Department of Geology and Mineral Industries (DOGAMI) has released new, unique, full color images of the Columbia River Gorge.
One of the things that makes these new images so amazing is the amount of detail you see on an image this size (5 feet by 6 feet and larger), Another thing that makes these images so stunning is our ability to manipulate the data that goes into creating the image. You can strip away all the vegetation and buildings so you’re left with a ‘bare earth’ view of the ground that is the most accurate representation of the landscape that has ever been seen. 2004
