[Gvsig_english] clean polygon? Issue with layersimportedfromOracle Spatial

[Juan Lucas Dominguez Rubio]

Hello, I have seen that when the user exits the editing mode, updated or new geometries are oriented using the SHP style (I presume this is done for the sake of uniformity,because the user might have drawn polygons with opposite orientations).
 
So you could do this:
 
- Add your Oracle Spatial layer to the view
- Export it as SHP (you get a bad shapefile) and add it to the view
- Start an editing session for that shapefile
- Choose the selection tool and select ALL geometries
- Choose the move tool and enter by hand in the console the same coordinates twice (origin = destination), for example:
 
0,0
0,0
 
- Finish the editing session and save the file.
 
I think the orientation will now be the one you prefer.
 
Regards,

Dear Fran, list.
uh-oh. I just overlooked the last posts. I am very happy that this
discussion takes place here. It would be very great, if this issue could be
solved in one of the next releases. It would be the best, if the check could
be done automatically. However, I ask myself, whether I should be able to
"repair" the shapefile (from oracle spatial) using the "clean"-function in
the geoprocessing toolbox. It would be perfect, if you could throw some
light on this option (and maybe some hints on what-to-fill in for dangling
and fuzzy-options) :))
BTW, using ogr2ogr, it is possible to change to orientation. But this should
not be the solution (it should be solved within gvSIG...)

Best,
Wolfgang
