Open Earth Open Earth Tools Open source management

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

An community of users since 2003 1. Delft 3 D is under strict version control; 2. data, models and tools usually aren’t 2. Make things beyond capabilities of single user: Google Earth DELFT 3 D preprocessing & postprocessing TOOLS: • output calibration • MODELS • input bathymetry • input meteo • input sources DATA • output validaton

What is Open. Earth: philosophy 1. 2. 3. 4. philosophy community repository delivery Cooperate

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

What is Open. Earth: community 1. 2. 3. 4. philosophy community repository delivery Cooperate

What is Open. Earth: 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 Open. Earth: repository version 1. 2. 3. 4. philosophy community repository delivery Cooperate central storage What Wikipedia does for knowledge what Sub. Version does for tools + data: “wikitoolia” or “toolipedia”

What is Open. Earth: web services version 1. 2. 3. 4. philosophy community repository delivery check this out Cooperate central storage What Youtube does for movies we want also for tools + data: 100% web services: “Datatube” or “Youdata”

How does Open. Earth do that: WORKFLOW s l o o t Version control and backup tools a t da data & scripts Web access to datasets from pluriform to standard format! Straightforward visualisation open source software

Source control for Dash. Board Technical session tomorrow

Community of practice: Open. Earth has a wide range of users (Building with Nature, EU FP 7 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 20 k€ - 200 k€ (6 - 60 minutes per commit) Crowd-sourcing did not lead to chaos: well-documented Repository of 1000’s of free matlab TOOLS • Delft 3 D toolbox • Google Earth toolbox • coordinate conversion • Organized workflow for DATA with open source tools: • facilitate input • facilitate calibration/vaildation
