Very cool, and really a beautiful image. Contour lines on a topographic map show the same data, but mapping the elevation to a color range and clipping out elevations outside the river's effects really make this unlike anything I've seen before. Edit: The original submission (see dang's post) references a similar set of maps[0] for the Mississippi River, which are equally beautiful and even more impressive.

- NelsonMinar 11y agoHere's another view I made of the Fisk map a few years ago. It's Google Maps style. http://somebits.com/fiskmap http://somebits.com/fiskmap This LIDAR map of the Willamette is really beautiful. Electric blue is an odd color for a data visualization, but it sure is striking.
