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.”

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

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;

22. How accessible are current maps?
• Costly
• Closed
• Often out of date

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

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

• It’s Free
• It’s Open
• It’s as current as the contributers make it

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

this is then an integrated map... tah-dah!
red is one day
blue is another day
black is the compilation
Cabspotting did this for San Francisco
(note for us) match this up with a map of london
this has been done for every major city in the world now.
to position in three dimensions, you need at least 4 transmitters
the distance each transmission travels through the atmosphere (at different angles depending on where the satellite is and the direction it is traveling around the earth
WAAS (wide area augmentation system)
EGNOS (European system)

this slide is great because it shows the details of the central area but then on the left you can see there are sections of town not yet done
like wikipedia in the early days the bookends were finished first, then the volumes were filled out.
all this was marked with gps, they’ve even marked each individual bus stop
