Geograph - photograph every grid square

Geograph publishes photos that illustrate the geography of Great Britain, Ireland and the Isle of Man.

For the first six years and 2 million images, Geograph contributors have been required to choose a primary geographical category for each of their images. They could either select one from a list or create a new one if what they wanted didn't exist. Some contributors limited themselves to a small number of very general categories (moorland, lake, buildings...) while others preferred to create much more detailed, often unique, categories (church (Roman Catholic) (former), artificial fish farming pool, bat hibernaculum...). The list grew to an unwieldy 9,000 categories, mostly of detailed photograph subjects. The primary geographical categories – which offered a broad-brush way of organising the archive – had got lost.

The system showed its limitations as the archive grew. For example, in this subject-rich photo http://www.geograph.org.uk/photo/1579473 the short title and description and single category (Watercourse) mean that other features go unrecorded, so will not be picked up in a search. Similarly in http://www.geograph.org.uk/photo/716196 the category selected was Lake. A search on Lake would return over 25,000 images – not very useful. The interesting detail in the description would only be found by a very specific search. In a third example http://www.geograph.org.uk/photo/514710 the category Artificial fish farming pool is unique, although the image would be found by a search for Fish farm. All these images would of course be seen in browsing their respective gridsquares. Photos with the minimum information will tend to be invisible to searches because searches are text-based. The solution is to enable contributors to choose multiple categories – tags – and one or more primary geographical categories – geographical context - that describe the content of the photo.

Of course, submitter knows best. The new system asks submitters to choose at least one geographical context from a fixed list of 46 very general options. If several of them apply, all their boxes can be ticked. At the same time, detail is encouraged with free-form tags which would previously have cluttered up the category list, and which can now be put to good use in narrowing down searches. So, geographical context and tags together should do all that categories used to, but without their limitations. In the Askern example several context boxes could be ticked: Lake, Village, Open space, Leisure; possibly Mining. From these alone a picture forms in the mind. Tags would fill in details of the birds, the tree, and the vanished historical features. The more information that can be attached to a photo the greater its value to the archive.

For performance reasons our search engine can only access the first 1000 results of a given search. This is in fact just like Google and other major engines.

If you are trying to view more images, there is a few techniques to use. The best one is to try to narrow your search results. Maybe adding a another keyword. Or even specifing a date range - for example limiting to only recent images.

If you order the results in date submitted (decending or ascending) order, you may be offered a link on the last page to create a new search from that approximate point forward (it does this by adding/changing the date critieria of the search) - in this way you can get though by using a number of seperate searches.

All images shown on the general photo pages fit within a 1024pixel-square area. If they are bigger than that when uploaded, the site software will reduce them to fit into that frame. If they are smaller than 640px, the moderator is likely to request a larger version.

Optionally, you can upload a larger version of the same photo and license that larger version with the same Creative Commons licence (unlimited free re-use by anyone for any purpose as long as credit is given) as the main image. To do this, select the largest image size that you are happy to contribute when prompted by the submission dialogue after uploading your photo in step 1. Geograph will produce the standard 1024px image as well as this higher-resolution one according to your request.

Site users can access these larger images by clicking on 'more sizes' above the main photo on the photo page.
