Willamette river channels

This lidar image of the Willamette River was originally the result of visual experimentation with color ramps and lidar elevation ranges.  The image is a digital elevation model of the Central Willamette Valley from Monmouth/Independence in the north to Albany in the south. The representative colors are compressed to a 50-foot elevation range from white in the lower elevations to dark blue in the higher elevations.
