Wow, that looks like quite a lot of work (have thought of doing Nottingham as I have the building outlines, but put off by the effort as it took me a while to manually classify neighbourhoods). So now:
- Portland - whole of Netherlands - New York - Helsinki we're moving fast. I hope to revisit my clustering of Portland buildings with a few refinements. I think I might look at immediate heterogeneity of building age (say for a weighted distance of 2-3 arcs on the graph), or calculate some kind of block-based coefficient. The problem still remains is that ideally I need a subset of data classified by hand to see if the clusters are genuinely useful. Places like NYC & Amsterdam may be much easier to do on this score.
