Geograph is a concept and open source code for a online website to create a comprehensive collection of photographs capturing every part of given region.
Currently there are three active projects, shown below - including a photograph from each.
Today's Photo of the dayNN3512 : Loch Lomond Vista by Adam Ward
Descending from the Corbett of Beinn a' Choin on a clear winter's day the views over Loch Lomond and Loch Long are lovely. Our tracks from the climb can be seen clearly to the left of the figure while some boats can be seen moored at Inveruglas.
