[Gvsig_english] sextante

[Antonio Ordóñez]

Hi all,

At the moment, SEXTANTE project is trying to do a help  more comprehensive (sextante toolbox). Victor and me are doing our best to improve this tool, so we will try to get it ready for you soon. However, there is a lot of work ahead here. 

At the bottom comes some references where you can get more information. I hope this helps.

Regards.

The SEXTANTE tools are adopted from the SAGA GIS project.
You could go to their web pages and try and dig up some English documentation on the algorithms.

That's what I guess. But to be honest, when using the tool I got only a raster with constant 0 as output. So I am not sure if I misused the tool or if it will do something totally different.
