The web based project Geograph British Isles successfully implementend geocubes on its website. geocubes clusters 1.25 million photos of the British landscape. The aim of the website is to offer a freely accessible archive of educationally useful, geographically located photographs of the British Isles. The respectable amount of 1,25 million photos didn't pose any problem to geocubes since our service works always independent from the number of geo-points at the same high level of performance.
