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
I share on giscloud.com the free view map with all layers, legend and attibution. 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.
Notice on both maps how zooming in and out preserves the features: are you aware of another vector web GIS today?
- giscloud.com put in a lot of work to allow this mashup, originally in stock WGS84, to be posted in the Ordnance Surgey's British National Grid projection - thanks Dino for this
- after visiting Cambridge University's S. Oosthuizen, population density data were provided by J. Bowring and added it to the giscloud map and the metadata file - thanks all for this]
