1. 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?

2. 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

3. What is OpenEarth: philosophy
community
repository
delivery
Cooperate

4. 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

5. What is OpenEarth: community

6. 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

What Wikipedia does for knowledge what SubVersion does for tools + data: “wikitoolia” or “toolipedia”

8. What is OpenEarth: web services

What Youtube does for movies we want also for tools + data: 100% web services: “Datatube” or “Youdata”

10. OpenEarth is already truly a community
TOOLS:
> 3000 commits!
> 60 active users
> 200 aanvragen
DATA:
> 1350 commits!
> 60 active users

12. Matlab toolbox for Delft3D
in addition to:
C:\Delft3D\w32\matlab\

13. Matlab toolbox for Delft3D-FLOW

14. Matlab toolbox for Delft3D-WAQ/PART

15. Matlab toolbox for SWAN-FLOW
Some guidelines to make community toolbox work:
* header line for contents
* cut ‘n paste example
* see also
* unit test
* copyright/disclaimer

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

27. 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

28. Source control for Dash DashBoard
Technical session tomorrow

29. 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.

30. Summary An active community with 60 developers within 2 years
100’s of users
3000 commits: value 20k€ - 200k€ ( 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
