Pierre,
I get the following error when I do an intersect:
NOTICE: UnsupportedOperationException: GeometryGraph::add(Geometry *):
unknown geometry type: N4geos4geom12MultiPolygonE
CONTEXT: PL/pgSQL function "_st_intersects" line 28 at assignment
SQL function "st_intersects" statement 1
ERROR: GEOS Intersection() threw an error!
CONTEXT: PL/pgSQL function "_st_intersects" line 28 at assignment
SQL function "st_intersects" statement 1
------
Any idea what could be wrong there? Could it be something wrong with the
postgis raster conversion? When I convert the image to a vector file, all
seems fine there.
