The People, the Commons, the Community
What is a community anyway?
People who want to make a Free map
Also...•People who want everything to be free
•People who love maps
•People who hate the OS
•People who want to make maps
•People who want to use data
•People who want to write software
The Problem: How to get all of these people
to do something coherent?
Non-monetary motivation

Give People Ownership
•Its your map, your project
•Ownership of the data
•CreativeCommons License - Trusted,
inpedendent third party
•Copyright assigned to the OpenStreetMap
Foundation
A Short Feedback Loop
•People want to see the results of their hard work
•Maps - Need to be rendered yesterday
•Software - Needs to be deployed before its written
•This can be annoying, but it means that the
community is working
Mapping Parties
• Gather in a place
• Map it exhaustively
• Have fun
Allow especially talented people to do
amazing things
•Committees don’t help much
•Massive standards don’t help much
•Talking doesn’t help much
Letting people do things
•Committees don’t help much
•Massive standards don’t help much
•Talking doesn’t help much
•Let the talented people do the amazing things

The Fallout

AND - Donated their entire Dutch road data set to OSM

Suppliers of Proprietary data will have to react
• More ANDs
• More PeoplesMaps
• More Tom-Tom map share
• More commercial use of OSM data
What the critics say
• How can you trust the data that someone
puts in?
• OSM format is useless for my GIS
• Where is the support?
•Where is the person on the end of the phone?
