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 day
SX7377 : Path to Bell Tor by Graham HornThis is a quick way onto typical Dartmoor moorland from the road at Bonehill Down. We had arrived in the area about half an hour earlier, after a long drive and looking forward to a lovely weekend. This first foray promised well.
