OpenEarthTools =
Open source management of
PMR-NCV
Data, Models and Tools for
marine & coastal
science & technology
.. and what about
wwww.OpenEarth.eu
An community of users since 2003
1. Delft3D is under strict version control;
data, models and tools usually aren’t
2. Make things beyond capabilities of single user: Google Earth
DELFT3D
preprocessing & postprocessing TOOLS:
• output calibration
• MODELS
• input bathymetry
• input meteo
• input sources
DATA
• output validaton

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

all collaborating is not enough
chaos
coordination needed
but no overall boss
like wikipedia
scripts mutate & spread: virus-like

Matlab toolbox for Delft3D
in addition to:
C:\Delft3D\w32\matlab\
Matlab toolbox for Delft3D-FLOW
Matlab toolbox for Delft3D-WAQ/PART
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

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.
