Hi,
I'm using the spatialite to do some spatials elaboration.
Spatialite will use the Geos . try-ing the test of validity on the
geometries I'm having some warning message .
Substantially there are three kind of message but I dont know the real
difference between the two type of message.
the message are:
"GEOS warning: Ring Self-intersection at or near point ..."
the other is :
"GEOS warning: Self-intersection at or near point ..."
and the third is
"GEOS: warning: Hole lies outside shell at or near point ..."
Thx,
--
