Right now there are three projects built on the Geograph Concept of collecting photos by 1km grid square. All Projects release the photos under a Creative Commons Licence.
The original site, created by Gary Rogers in 2005. There is also a dedicated homepage for
Geograph Ireland, but its the same content as the parent site.
Hansjörg Lipp,
took the geograph.org.uk source code (its
open source!) and created a sister project collecting photos of Germany.
Barry Hunter started a very small project for the Channel Islands, only 248 squares.
