YOU? OpenEarth PMR-NCV … OpenEarthTools = Open source management of Data, Models and Tools for marine & coastal science & technology wwww.OpenEarth.eu PMR-NCV .. and what about YOU?

An community of users since 2003 Delft3D is under strict version control; data, models and tools usually aren’t Make things beyond capabilities of single user: Google Earth DELFT3D preprocessing & MODELS input bathymetry input meteo input sources postprocessing TOOLS: output calibration output validaton DATA

What is OpenEarth: philosophy community repository delivery Cooperate

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

What is OpenEarth: community philosophy community repository delivery Cooperate

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 Cooperate Project 1 Project n Models Data Tools

What is OpenEarth: repository version philosophy community repository delivery Cooperate central storage What Wikipedia does for knowledge what SubVersion does for tools + data: “wikitoolia” or “toolipedia”

What is OpenEarth: web services version philosophy community repository delivery Cooperate central storage check this out What Youtube does for movies we want also for tools + data: 100% web services: “Datatube” or “Youdata”

DATA DELFT3D preprocessing & postprocessing TOOLS: MODELS input bathymetry input meteo input sources postprocessing TOOLS: output calibration output validaton DATA

Use of data directly from OPeNDAP server Delft3D-Quickplot Delft3D Quickplot Rookies can do this

How does OpenEarth do that: WORKFLOW tools data Version control and backup Web access to datasets Straightforward visualisation tools data & scripts from pluriform to standard format! open source software

Source control for Dash DashBoard Technical session tomorrow

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.

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
