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:

• selected land cover from H.C. Darby's publications on the Middle Ages and later
• administrative and geographic boundaries from UK Ordnance Survey OpenData
• surficial and offshore geology from British Geological Survey web mapping services
• and global coastline for a lightweight frame of reference from US NGDC GSHHS

Below is a dynamic quick view of the 1332 Assessment, counties and geology explained here and here - also posted here with Google and Open Sreet Map underlays. In the public domain or with specific rights, data are posted under Creative Commons Attribution - Non-Commercial - Share Alike 2.0 UK: England & Wales Licence. Full metadata are posted here, showing the detailed attribute data.

I share on giscloud.com the free view map with all layers, legend and attribution. Their distinction is posting vector data with GIS functionality on full view maps: Original shape files are uploaded in PostGIS for full vector GIS function, and WMS rasters post in original British National Grid.
