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.

History

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:

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.

General OpenEarth documentation

Various presentations and lectures on (the use of) OpenEarth. Also see our agenda

Tech Notes and Data tutorials

Dedicated solutions for specific issues, focused on 3 languages and one GUI can be found using the links below.
