Curvature helps you plan trips and discover twisty roads anywhere in the world.
The goal of this program is to help those who enjoy twisty roads (such as motorcycle or driving enthusiasts) to find promising roads that may not be well known. It works by looking at the geometry of every road segment and adding up how much length of the road is sharp corners, broad sweeping curves, and straight areas. The most twisty segments can then be output as KML files that can be viewed in Google Earth.
