Collective memory, a wiki for tools

Core of the OpenEarth philosophy on tools is that by systematically storing, maintaining and disseminating data routines, I/O routines, engines, applications and programs at a central location, slowly but surely a toolbox emerges that acts as a collective memory to which analysts and end users naturally gravitate regarding their basic information needs. The long term focus of the approach promotes collaboration and the exchange of ideas across the artificial boundaries of projects - and even companies - which is beneficial for the coastal/marine/hydraulic and environmental research and engineering community as a whole.


The idea to collect, maintain and disseminate data, models and tools used by and developed at Delft Hydraulics was first put forward in 2003 by Mark van Koningsveld as quantitative support for, and in fact as an extension of, the Frame of reference method he developed during his PhD research. The initiative quickly merged with similar intiatives by Gerben de Boer and Fedor Baart that emerged at roughly that same time. Thir combination formed OpenEarthTools, that has since grown to accomodate contributions from over 150 user-developers, as is shown in this activity visualisation:

OpenEarth and other web-hosted tools collections

Related initiatives, which OpenEarth does not intend to compete with, come in a number of flavours: general purpose: Sourceforge, github (‎), dedicated to specific analysis languages: R-forge, Matlab Central, Python Package Index. In contrast to these initiatives, openearthtools is a collection dedicated to the application area of marine and coastal science and engineering. OET currently mainly hosts Matlab and python code.

Getting the OpenEarth tools

All openearthtools are stored in-the-cloud at the Deltares open source svn server that also host the open source numerical models Deft3D and Xbeach. Access is free but requires registration at the associated OSS (Open Source SoftWare) portal first: Here is some documentation on Joining OpenEarth or Getting started with the OpenEarthTools svn tools collection.

Documentation, tutorials and tech notes

A huge collection of tools need proper discovery and documentation facilities. The remainder of this page links to the various sources of documentation on OpenEarth and its tools. There are separate tech notes for the three analysis languages that OpenEarth fosters and supports: MATLAB, Python and R.
