Today's topic is the Geograph Project, a crowd-sourced project that combines photography and maps via a simple idea: volunteers take photographs at each Ordnance Survey grid square. Started in 2005, the project recently celebrated the uploading of its 7 millionth photo upload, and has a thriving community with over 13,000 contributors across the British Isles.
