  5. 5. Why maps? “Because maps are a visual tool for sharing information with others. Because they can be produced by many people and combined together to tell stories about complex relationships. Because maps are never finished and only tell part of a story that can constantly be expanded upon. Because power exists in space, struggle exists in space and we exist in space. Because we cannot know where we are going if we do not know where we are from.” - Notes for a People’s Atlas of Chicago http://chicagoatlas.areaprojects.com/about/ 5

  14. 14. Why Mapping? “ Certainly we wanted to use the mapping to help us figure out what a neighborhood was, but we also wanted to use the mapping as a kind of organizational tool, as a way of bringing the neighborhood together and helping it to see itself.” - Denis Wood, The Power of Maps 14

  21. 21. 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; 21

  25. 25. A thought... “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 25
  26. 26. How is OpenStreetMap different? 26

  35. 35. “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 35
