Overview
• Mainstream at last!
• Data sharing
• A real-time, multimedia view of the world
• Crowdsourcing

GIS was a specialized backroom technology for many years

Finally, geospatial data is just another data type

Here’s a print of Chinatown, San Francisco.
Instead of gargoyles, we’re using more appropriate bits of icon and text to recognize the corners.
Here you can see that someone has walked around Green Street and noted address information and a few businesses.
This is not information that you’d be able to get from a satellite image.
It’s also information that don’t really need a GPS for: the roads are already in place, but they need extra eye-level information.

3 rules for evolvable systems
Clay Shirky, 1996shirky.com/writings/evolve.html
Only solutions that produce partial results when partially implemented can succeed
What is, is wrong
Orgel's Rule: "Evolution is cleverer than you are".
Evolvable
Centrally designed

What about quality?
“OSM quality is beyond good enough, it is a product that can be used for a wide range of activities”

Financial Revenue $853m (~€604m) Data creation & distribution costs $396m (~€280m)
“Creating, maintaining and delivering a comprehensive, high quality map database is a
multi-step, labor-intensive process. We currently employ over 270 employees in our centralized production facility and a global
workforce of over 700 geographic analysts in 32 countries”
