Hi Peter: Adding the following metadata to the layer returns a multipolygon for
me:
METADATA
"ows_geomtype" "Geometry"
END
Without specific direction on geometry type it may be that MapServer is
capitalizing on the layer type or something like that.

Subject: [mapserver-users] MultiPolygon layer requested as GeoJSON is returned
as Polygon
Hi,
I have a layer with one MultiPolygon feature. I issue a request for the layer
as GeoJSON, like so:
curl
"http://localhost/mapserv?MAP=/usr/src/mapfiles/busted.map&service=WFS&VERSION=1.1.0&REQUEST=getfeature&typename=should_be_multi&OUTPUTFORMAT=geojson";
In response, I get a single feature, but it has been converted to a Polygon.
{
"type": "FeatureCollection", "name": "should_be_multi", "features": [
{ "type": "Feature", "properties": { }, "geometry": { "type": "Polygon",
"coordinates": ... } }
]
}
The returned polygon has interior rings, one of which should actually be a
separate polygon with its own interior rings. I think this is wrong and the
geometry type returned by MapServer should be MultiPolygon. Can anyone help me
understand what is going on?
Here's the feature as a MultiPolygon I expected to receive:

Here's my MAP file:
