Geograph and Domesday Reloaded
David Hawgood suited up for Geograph
Many of the 2011 pictures appearing in Domesday Reloaded so far have come from members of the "Geograph" community.
The Geograph project has much in common with the original idea of the BBC Community Disc. David Hawgood, who has contributed some 6000 photographs to that project, here writes of how Geograph members have been helping with Domesday Reloaded today...
Geograph Britain and Ireland project aims to collect geographically representative photographs and information for every square kilometre of Great Britain and Ireland. Thus it has close parallels with BBC Domesday Reloaded.
Since early 2005, over 10,000 members have contributed almost a quarter of a million images covering over 260,000 grid squares, almost 80% of the total. For each image there is some description or keywords, grid references of subject and photographer, and date taken. There is also a section of map from Ordnance Survey, who sponsor the project.
"As well as being available at http://www.geograph.org.uk/ and the schools site, images are archived by the British Library, so they should remain available in future by quoting the image number. Images are published under aCreative Commons licence so that users can copy them freely.
"Since the BBC launched the Domesday Reloaded web site some Geograph members have gone out to take photos recreating the Domesday photos. These have been published on the Geograph website and submitted to Domesday Reloaded, and more will appear in future.
"Facilities have been added to Geograph to provide conversion between D-Block number and grid reference.
"A Domesday D-Block is 12 of the National Grid 1km squares, 4km East-West by 3km North-South. The menu bar at the bottom of every Geograph photo page includes "More links for this image". One of those links is "Domesday Reloaded" to the appropriate D-Block page of the BBC site. The Geograph page for a grid square e.g. SK0000 has a similar "More links" item.
"Geograph search facilities now include a D-Block Finder. Entering the D-Block number in the GridRef box displays a Geograph page with photos from the grid squares of the D-Block. For example, entering GB-400000-300000 gives twelve thumbnails from grid squares with SK0000 bottom left.
"Search facilities in Geograph may also help users of Domesday Reloaded locate the positions of the 1986 photos. You can search by text words and place name. Entering a place name shows all places from a gazetteer including that name, with county, district, borough or equivalent. Entering words from the Domesday Reloaded description may find a photo near the 1986 one. The "More links" from photo pages and grid squares includes links to various maps and aerial views.
"Finally, a note on the relationship between D-Block numbers and the National Grid:
"The D-Block number shows the number of metres East and North from the National Grid false origin. National Grid references give each 100km square a two letter reference for England, Scotland, Wales and the Isle of Man. For Ireland the 100km squares have single letter references.
"GB-84000-6000 is in the "bottom left" 100 km square SV of the GB set and stretches North and East from SV8406 in the Isles of Scilly. D-Block GB-400000-300000 is in the Midlands near Walsall with grid square SK0000 at the bottom left of the 4x3 block. D-Block NI-332000-372000 is around Belfast in Northern Ireland with grid square J3272. CI-530000-5476000 is St Peter Port in the Channel Islands - Geograph Channel Islands is separate from Geograph Britain and Ireland and does not have the Domesday links so far."
