Pretty Map!

One of the things we been looking recently on Geograph, is guageing how ‘recent’ our coverage actually is. We impose no restriction on when photos where taken – because historical images are useful – not to mention every photo is historic by definition as soon as its taken!
'Age Map'
Anyway the point of this post is in the process decided to try plotting a map showing the ‘age’ of the latest photo in a square – to see that recentness. The result is here:

OMG, quite aside from what it shows, it looks beautiful. (To my untrained eye!)
