What is OpenEarth: community
• Prisoners dilemma & Tragedy of the commons: 1+1=3 sometimes sharing does not work, but usually it does • OpenEarth accepts some asymmetry in sharing: it is the player that keeps the sharing going

Community of practice: OpenEarth has a wide range of users (Building with Nature, EU FP7 MICORE, Delft Cluster etc.). Building with Nature facilitates training sessions.

What is OpenEarth: community needs structure
• • • • • • all collaborating is not enough chaos coordination needed but no overall boss like wikipedia scripts mutate & spread: virus-like

Summary
• • • • • An active community with 60 developers within 2 years 100’s of users 3000 commits: value 20k€ - 200k€ (6 - 60 minutes per commit) Crowd-sourcing did not lead to chaos: well-documented Repository of 1000’s of free matlab TOOLS • Delft3D toolbox • Google Earth toolbox • coordinate conversion • Organized workflow for DATA with open source tools: • facilitate input • facilitate calibration/vaildation
Web access to datasets from pluriform to standard format!
