[Gvsig_english] Geoprocessing: Difference-Tool

[spatialjoe]

Hi Rolf,

Benjmain is right. Your error message says.
"found non-noded
intersection between LINESTRING ( 236.80441645812243 356.21349653881043,
236.529304722324 349.8171486798674 ) and LINESTRING ( 236.80441645439714
356.14471860881895, 236.04785918071866 356.14471860881895 )"

If you only have polygons this may indicate that this specific polygon is
not "closed" and therefore is recognized as line feature.
See attached shp which I converted from the wkt info in the error message.
Not sure about projection and so on but maybe this helps finding the faulty
feature.

best,

Johannes
