East Anglia Fenlands wrap-up

It may be time to run an overview, two years on this personal project on East Anglia, the last step of which was reviewed by socium.co.uk:

Even more temporal maps

I posted here my webmaps from the East Anglia Medieval Fenlands project. I have now posted these on arcgis.com for use in ESRI maps: Watch future posts on time-enabling this project, and adding geo-processing to further examine these derived data. Note also that ArcGIS is available for personal use an research for $100 worldwide now.

Reading Social Web Maps

Look at this map, and what it doesn't show is as instructive as what it shows. You guessed it, it's the low number of social media hits - anyone on the blogosphere or twitterverse would find those numbers on the low side, especially considering the passion current events in Egypt generated on the ground and online - and I wager doesn't reflect poor map making, but rather the fact the web was tampered with during the events in Egypt.

5 Ws for citizens-as-sensors

Des Kilfoil at the CBC in Calgary, Canada introduced me 20-odd years ago to the 5Ws, the basic tenets of any investigative reporting, from journalists to police, from Wikipedia:

• Who? Who was involved?
• What? What happened (what's the story)?
• Where? Where did it take place?
• When? When did it take place?
• Why? Why did it happen?
• How? How did it happen?

The Big Easy button

Building geoinfo from the ground up is patent in this Gov2.0 presentation on citizen-focussed geoweb at the Greater New Orleans Community Data Center toward sustainability in the Big Easy:

Gathering clouds over the horizon, Part II

I posted earlier an example of a simple Google Map reading a list of Olympic cities - this was part of a list of Google and OpenLayer maps I built over the years on my old website - I also posted a nifty display of plate boundaries in Google Earth here. Following on the discussion of new web mappping (Part I of this post), I recreated both on giscloud.com to see how the two implementations compared.

Historic Fenlands Mashup

[See updates at bottom, and predecessors Medieval Fenlands GIS and Post-medieval Fenlands GIS]

Here is a mashup on giscloud.com of the geographic history of land cover and surface geology of East Anglia since Domesday based on:

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.

Webmaps, history, climate and geology

Chatting with local history buffs brought up amazing facts about climate change and sea level rise since the Middle Ages in East Anglia. One book's sketch map relates how the North Sea coastline differed from today, and how that affected Anglo-Saxon socio-economics there before and after the Norman conquest and the Domesday book.
