[Gvsig_english] R: Re: WMS and WCS raster pixel dimensions

[fla83tn at libero.it]

I just posted the same problem on the gvSIG mailing list!!!
I have to solve the 
problem someway, if nobody fix it I will do it myself..

Thank you all for the 
support!

each ROI and they can be copy-pasted further.  I can send you the script and 
some screen captures which show how the workflow goes if you are interested.
