This presentation is from the University of Nottingham's Open Data Master Class series from November/December 2010. http://bit.ly/opendataMC It introduces the practical work ofthe classes but also has brief notes on linking statistical data to its geographical references. Acknowledgement for source material goes to the Geo-Refer project ( http://www.restore.ac.uk/resources/grefer.php ) and to Mark Monmonier's "How To Lie With Maps".

2. Hands-on Practical
• An opportunity to work with real Open Data
• Relatively simple examples but designed to
link thematically to the Geovation challenges
• Mostly geographically related analysis, though
some analysis in Excel too
• First, some introduction to key concepts

7. So many reference zones to choose from...

8. Zones Matter!

21. Practical work
• Divided into three phases (no formal break)
• Phase 1: introduction to taking a table of
points & related attributes, doing some data
analysis in Excel then plotting the points on a
map
• Phase 2: looking at joining data from different
sources to produce a new picture of an area
• Phase 3: advanced challenges.
– First leads on from Phase 2: further analysis
– Second relates to joining to complex admin units
