Post-medieval Fenlands GIS
Let's look at the geographic history of land cover and surface geology of East Anglia after the Civil War , based on Ordnance Survey OpenData and British Geological Survey web mapping services (WMS). My previous posting discussed H.C. Darby's historic & geographic economics of East Anglia Fenlands between the Domesday census and the Civil War.

A recent twittersation with @rollohome had me pull out these screen shots from Google Maps - it doesn't appear to give proper driving directions around complex British roundabouts - I thought this was a curious counterpoint for Earth Day, as we go round&round...

Medieval Fenlands GIS
[Update 5: see its latest reboot on a new community engagement project here
Update 4: Data on ShareGeoOpen is now on successor Edinburgh Datashare
Update 3: see subsequent story with Ordnance Survey and 1SpatialOnline validation
Update 2: see web mashup with later historic data and more on data repositories
Update 1: see companion Post-medieval drainage of the Fens from same source]
The recent release of UK Ordnance Survey OpenData opened the opportunity to post H.C. Darby's data from The Medieval Fenland and The Drainage of the Fens of East Anglia in the eastern UK. And parishes are the geographic unit that remained constant since the Middle Ages.

No such thing as a free lunch
To great press and technocrati fanfare, the UK Ordnance Survey freed up its data... somewhat! This was promptly announced on mapperz and Ernest Maples blogs. And commented on as far away as the US west coast by Ed Parsons and Geoff Zeiss currently in America - does location matter?
