I try perform a clip operation on a spacial database table. Selecting
the geometry works so far ..
intersection (the_geom,GeomFromText('BOX3D(120 30,150 40)'::box3d,-1))
the_geom && GeomFromText('BOX3D(120 30,150 40)'::box3d,-1)
BUT when I dump the result to a shapefile via shp2pgsql the lineshapes
are dissolved into its points. My question now is, how can I perform a
clipping operation on lines or polygons which cuts the object at the
clipbox edge ??
Thanx for any help !
