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!)

This time its TG and covers East Anglia and Norwich area, covering 1991 land squares. There is more on the overall progress here, which shows the coverage by Myriad (which by the way is a Geographism for a 100x100km square on the National Grid)

To try to showcase these have been creating some Zoomable viewers to really see the coverage:

Geograph Mosaic Collection

Unfortunatly they require too much manual work to be part of the real site (creating a ‘printable page’ at the appriate scale, stitching all the images, and then running it though zoomifies utility) – but it would be really good to get a Flash programmer to be able to create a viewer like this that runs directly off Geograph tiles!
