udig got a spatial toolbox

I think to it as a milestone to which I contributed a little during the years, even if the full merit needs to be done to Andrea Antonello and Silvia Franceschi: "the Hydrologis".

The idea was to give a transparent (encapsulated) way to add spatial models to a GIS. As told in previous blogs, the way was found in following the OMS3 framework ideas, after having tried hard with OpenMI. Andrea did more by using OMS3 annotations to automatically create the input-output interface, and manual like help, to any OMS3 compliant module. Any information can be found at

udig spatial toolbox a.k.a. OMS3box. However, do not use the 0.7.1 code but use the more recent one that can be found at the jgrasstools download page.

I do not know if Andrea and Silvia fully realize the importance of what they created. It is a big jump to a new type of GIS where the usual paradigms for connecting models, data and visualization, are suddenly changed.

Researchers can now program their model following the OMS3 lines, and having them fully endowed with graphic I/O, help, without taking care of the details of making it.

Certainly programming a Jgrasstool is still a challenge for novices, and much work has to be done to smooth the learning curve of it. Especially writing manuals ;-)

Great work Andrea and Silvia: congratulations !
