Create a variant that identifies dirt roads #5

As a motorcyclist, it would be interesting to be able to detect dirt roads or overlay data in a similar way the we can do with curvature to identify dirt roads. I think road surface is identified in OSM. So being able to get generate the same output that you do now but instead of curvature, just identify dirt road roads would be a very cool feature for route planning.

Hi Stephen, you are in luck: The surface.py script included in the repository does just that. :smile: Here is an example of the output for Vermont: http://www2.adamfranco.com/curvature/kml/north_america/us/vermont.surfaces.kml

Road-surface tagging is generally pretty spotty in the US at this point and could use a few more folks adding tags.
