  10. 10. Paleogeography
  11. 11. Neogeography
  12. 12. Essentially, Neogeography is about people using and creating their own maps, on their own terms and by combining elements of an existing toolset. Wikipedia

  22. 22. OpenStreetMap
  23. 23. §
  24. 24. Why OSM? • Geodata isn’t • Free • Open • Current • Wiki is obvious next step • It’s just fun
  25. 25. Some Quotes
  26. 26. Quote 1 “It’s absolutely possible for a bunch of smart guys with the technology we have today to capture street networks, and potentially the major roads of the UK and minor roads” Ed Parsons, ex-CTO Ordnance Survey
  27. 27. Quote 2 “If you don’t make [lower-resolution mapping data] publicly available, there will be people with their cars and GPS devices, driving around with their laptops .. They will be cataloguing every lane, and enjoying it, driving 4×4s behind your farm at the dead of night. There will, if necessary, be a grass-roots remapping.” Tim Berners-Lee
  28. 28. Quote 3 “You could have a community capability where you took the GPS data of people driving around and started to see, oh, there’s a new road that we don’t have, a new route .. And so that data eventually should just come from the community with the right software infrastructure.” Bill Gates
  29. 29. We make beautiful maps
  30. 30. ...which we give away
  31. 31. Using OSM
  32. 32. Workshops Or, Map as Party
  33. 33. Fallout
  34. 34. A-Z Norman Dennison, director of Geographers' A-Z Map Company, confirms that Lye Close is a lie, which will now be removed. quot;The idea is to put something on the map to protect copyright,quot; he says. quot;We try to put it in an area or a part of a road which would not be misleading to the ordinary person in the street. They have been put in out- of-the-way places.quot;
  35. 35. Postcodes

  37. 37. Coase’s Penguin (Yochai Benkler) Commons-based Peer Production: •Non-monetary motivation •Discrete multi-size pieces •Low-cost integration
  38. 38. Coase’s Penguin (Yochai Benkler) Commons-based Peer Production: •Fun •Takes 5 minutes •Easy

  51. 51. • Consultancy • Development • OpenStreetMapData (cleaned, nice formats) • Proprietary data, using OpenStreetMap tools (much cheaper)
