For using SEXTANTE gvSIG CE is much more better than 1.11, since the version in 1.11 is and old one and is not correctly installed. Please use gvSIG CE instead of 1.11 1.12 should be better and have the latest SEXTANTE release Regards Victor 2012/5/9 Antoni Riba <antoniriba@xxxxxxxxx>: > Hi list, > > This is my first time in list. > > I have a problem with the Sextante vectorization algorithm. > > Working with gvSIG 1.11.0 final (Build1305) on Windows XP, with Java > 1.6.0_06. > > I vectorized polygons but some of the polygone are not well done.
