2. 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.

13. 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

14. How is OpenStreetMap
different?

15. “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

16. quot;OpenStreetMap is a project aimed squarely at creating
and providing free geographic data such as street maps to
anyone who wants them.quot;
