[Gvsig_english] gvSIG 2.0 and sextante?

[Victor Olaya]

I guess there is no need to discuss this too much, but, like Fernando,
I would like to clarify  one thing:

 As Fernando said, it's clear that SEXTANTE (I am talking about the
Java version here...) did not depend on me 100%. It's been more than a
year since I made my last commit to the project, and the project has
kept growing and improving. Ben is doing great work, but Fernando
himself, or Francisco Puga, among others, have also commited since
then. It might not be a huge number of people, but is larger than the
number or people working on SEXTANTE from the gvSIG Association...and
the work they are doing is not smaller (the repos do not lie, it's
easy to check their history...) And I guess we will all agree that for
a newcomer it is easier to join the gvSIG CE team, gain repo access,
etc,  than joining the official gvSIG team in the same conditions, so
getting a larger SEXTANTE developer base seems more likely to happen
in the CE side.

"On one hand, in order to improve the usability that we started in gvSIG
2.0, we dealt with the option to have an unified geoprocessing manager,
where the user can find any geoprocess available in gvSIG. And our first
objective, from the point of view of the product, we had to include all
the geoprocessing tools of the gvSIG 1.x versions for the users. For
that, in gvSIG 2.0 you can find the geoprocessing tools from the "old"
gvSIG geoprocessing manager (clip, buffer, union...), the raster
geoprocesses of gvSIG, and the geoprocessing tools from the Sextante
library."

I agree that this is a good thing, and it is sad that this development
was not incorporated to SEXTANTE just for a matter of licenses...

Cheers
Victor
