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
SX1496 : Crackington Haven by Paul DixonTaken from the cliff around SX140972, but covering a good proportion of the SX1496 grid square with Crackington Haven nestling at the bottom of the valley. This was taken in 2003, before the 2004 floods which washed away the car park and footbridge.

Random photo (doesn't have a daily photo)
WV5454 : Path on Les Landes by Gerald EnglandA pathway on the heathland at Les Landes. There appears to be four puddles but the front one is actually a dead rabbit. The only tracks in the mud appear to be made by horses' hooves.
www.geograph.org.ggGeograph Britain and Ireland, also has a slightly simplified site schools.geograph.org.uk intended for use within Schools.
... and a sub-project just focusing on images in Ireland, www.geograph.ie.
Geograph Germany/Deutschland, also has a German/Deutsch language version at geo.hlipp.de.
