Maps are forever (Part II)

I wrote earlier about a 1610 map from the Harvard University Library of the Cambridge UK region, a snapshot of which I simply edited the tear and restored it by eye-balling it in Photoshop Elements. I detailed before some local history and geology too.

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.

The power of context, Part IV

Two anecdotes on remote sensing and environmental monitoring highlight some issues in measuring and predicting the current Gulf of Mexico oil rupture.

bp oil rupture, Part II

Here the latest from bp itself at the current NOC show in London.

News swirling around the incident in the Gulf of Mexico (GoM) compels me to draw out some salient facts and gather them here to help the uninitiated (I did this yesterday for my in-laws). This blog title is from the last slide of the video in my last blogpost.

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.

[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.

Rebranding Conferences - Part II

The Finding Petroleum (FP) January Conference at Inmarsat in London was the first topic on rebranding conferences. Yesterday's Forum on collaborative technologies at the Geological Society, London was a second type of offering. According to FP founder David Bamford, forums are:
