And now for the rest of the cities (I still need to get the US data
though). I've checked all the PPLC (capitals) and PPLA (regional
capitals I think) entries in the geonames database. I've shrunk the
search area down to 0.5 either side of the place, which is probably
still too big.
Top 10

boroughs will be sharing a set of points I'd think)

There's lots of work still to do on tidying up the algorithm, but just
wanted to share some of the stats in the mean time.
Cheers,
