I'm thinking about a new project, so I don't have data yet, but I plan on collecting GIS information for houses within a state.
Usually in the U.S., these dead-end streets will have a large circle for cars to turn around in, meaning the fronts of each house on the cul-de-sac point toward the center of the circle.
In general, my question is how to locate a subset of data clustered in a circular pattern on a 2D grid. If the same technique could allow me to locate dead-ends, that would be useful, but not required.
I'll probably need to use a logistic classifier, but I'm not certain what the hypothesis should look like. If this is a well-known problem, I didn't know the keywords to do a proper Google search, so pointers in that direction would be helpful as well.
