Another problem for me to work on is how to ‘cluster’ users, as things stand with my map, users will only be clustered if they have exactly the same latitude and longitude – which fairly quickly starts to break down – on the image above there are several pins around Milton Keynes and it’s not really obvious exactly how many users are there – or whether there are more pins hidden behind the pins you can already see.

So I’m going to look to see how we can do the clustering more sensibly (perhaps at different resolutions of Google maps), this was solved quite well in BuddySpace, so I’m going to have a look at the algorithm used there (see the tech report on it) and see if I could apply the same algorithm, or if other algorithms have been developed in the last few years.
