[Gvsig_english] WFS, Sextante

[Dietrich Schröder]

Antonio,
I used the stable version. I have just now installed the nightly build.
Unfortunately, there were some problems with GUI, the SEXTANTE toolbox was
not properly accessible. It comes up with some additional window to
configure the toolbox, but it didn't work. So I've used a workaround to test
the vectorization, that is using the Modeler, here the tools are accessible.
But he result is the same: overlapping polygons as you can see from the
screenshot.

Yet I've not checked the topology approach, I will do that later.

By the way, still I have the problem of deactivated tools in the modeler,
even though I've loaded some vector layers. In particular, all the tool in
"tools for polygon layers" are deactivated.

Best Regards 

Dietrich

Dietrich,
which Sextante version are you using? I have reclassified a DTM in
reference to some heigth classes and then I applied the Vectorize raster
layer (polygons) tool: it works fine with the latest Sextante nightly
build [1]. There's no trace of overlapping polygons.

Best regards,
Antonio
