    • Geodata collection for the twenty-first century Nick Black 20th September 2007
    • §
    • Mapping Parties • Gather in a place • Map it exhaustively • Have fun
    • Stats •11,000+ users •1,000+ users editing / month •10-20 million objects in db
    • Data: UK-US comparison
    • US GeoData Maket Price ‘Quality’ 100 ‘%’
    • US GeoData Maket Price TIGER-derived (mostly) TIGER ‘Quality’ 100 ‘%’
    • UK GeoData Maket Price ‘Quality’ 100 ‘%’
    • UK GeoData Maket OS Price OSM ‘Quality’ 100 ‘%’
    • UK GeoData Maket OS I’m ignoring ex- Price copyright data as its place is very debatable OSM ‘Quality’ 100 ‘%’
    • UK GeoData Maket OS Price OSM ‘Quality’ 100 ‘%’
    • UK GeoData Maket OS Price OSM ‘Quality’ 100 ‘%’
    • UK GeoData Maket OS Price OSM ‘Quality’ 100 ‘%’
    • We’ve seen this before
    • OS Market Windows Price Linux ‘Quality’ 100 ‘%’
    • OS Market Windows (Think price per Price feature) Linux ‘Quality’ 100 ‘%’
    • So what is valuable within the OSM stack?
    • 0 Value Lots
    • Aerial Imagery 0 Value Lots
    • NPE Aerial Imagery 0 Value Lots
    • Software NPE Aerial Imagery 0 Value Lots
    • The People, the Commons, the Community Software NPE Aerial Imagery 0 Value Lots
    • 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?
    • Use Force Requires a lot of resources

    • Create an ideology Ideologies are exclusive and often end in disaster http://www.flickr.com/photos/mshades/493511263/

    • Non-monetary motivation
    • Non-monetary motivation Give people ownership
    • Non-monetary motivation Give people ownership Create a short feedback loop
    • Non-monetary motivation Give people ownership Create a short feedback loop Allow especially talented people to do amazing things
    • Coase’s Penguin (Yochai Benkler) Commons-based Peer Production: •Non-monetary motivation •Discrete multi-size pieces •Low-cost integration
    • Coase’s Penguin (Yochai Benkler) Commons-based Peer Production: •Fun •Takes 5 minutes •Easy
    • 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
    • Allow especially talented people to do amazing things
    • 'It's my belief that open software and data projects are much the same... They don't progress smoothly but in fits and starts. Thus far those punctuations in equilibrium have been the result of single efforts. To point out some of them, they are the rails port, the introduction of mapnik, the move from java to ruby, the first mapping party, josm, aerial imagery. These are largely the result of one person having some time and/or insight to change things.' Steve Coast, July 2007
    • Letting people do 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
    • I know what you are thinking... • 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?
