In a guest blog post, Darren from the Ordnance Survey Eduction Team tells us about a key milestone of the Geograph project.

A national online photography project supported by Ordnance Survey reached a major milestone this month.

The Geograph project aims to capture an image for every grid square across the British Isles and the project has now registered its 3 millionth image.

11,000 users across the country have contributed images in the 7 years the project has been running.

Geograph is a fantastic free resource for schools to use.  All the images within the site are geo-referenced to an OrdnanceSurvey map.

It allows teachers to access images from northerly point of Shetland to the Scilly Isles in the south the site shows photography covering 80% of the grid squares across British Isles.
