Temporal GIS from the Current to Distant Past from Maps to Satellite Imagery

East Anglian economic geography from 1087 to the present was posted on sharegeo.ac.uk and on giscloud.com; it is now on arcgis.com to further explore it over time. The study of economics and land cover are pushed back as far as possible: early 19th c. for surficial geology, 14th c. for measuring wealth via tax assessment, and 11th. c. for the same via plough shares! How come? Parishes are a persistent geographic unit that allow mash-ups over almost a millenium…  Not only that, but changes in land cover mapped over the last 150 years are detailed by satellite imagery change detection in the past generation.

  1. Thanks for linking to ShareGeo.  A big thanks to Andrew Zolnai who posted the data on ShareGeo.  I think sharing data is a great idea, it helps the wider GIS community in so many ways such as providing data for users to experiment and learn with and it should make us more efficient; why re-invent the wheel when it already exists.

    If anyone has any data that they would like to share with others, please head over to ShareGeo and get in contact through the Contact US form.

    • You're welcome… happy to promote such ventures as yours! See my latest blogpost on a student's effort along the same lines (from another uni I'm afraid  ;-]  ). Back to my post on Sharegeo, you might be happy to learn that the somewhat cumbersome Volunteer Geographic Information (VGI*) I suggested to you then is being eclipsed by the more elegant Crowdsourcing (*: WABA = what! another bloody acronym?)
