Hi all,
I'm using PHP-Mapscript with GEOS (Mapserver 5) to get a WKT-String from
a POSTGIS-Table:
$mywkt = $shpobj->toWKT();
Everything works fine for POLYGON, LINESTRING and POINT - tables.
If I try the "toWKT()" Method for MULTIPOLYGON-Tables I get back a
POLYGON WKT-String.
What can I do?
Sven,
The MapServer internal geometry model does not differentiate between polygons
and multipolygons so it is very hard to preserve the original multipolygon
without doing a great deal of processing on the rings held by mapserver to
determine whether they are really holes in a polygon or distinct polygons
in a multipolygon.
Basically, you are out of luck.
Best regards,
