Interesting - I too am using GDAL 1.9. Can you suggest anything else I can try? I'm kind of at a loss as to how to narrow this down further. Thanks for trying it out.

I've just tested adding your outputformat definition in a Mapfile and I get the bbox at FeatureCollection level : $ mapserv QUERY_STRING="map=test_geojson.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=popplace&OUTPUTFORMAT=geojson" Content-Disposition: attachment; filename=result.dat Content-Type: application/json; subtype=geojson { "type": "FeatureCollection", "crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:EPSG::3978" } }, "bbox": [ 2279399.0, -55344.50390625, 2600377.0, 461586.8125 ], "features": [ ...snip... ] } I've only tested with mapserver master and GDAL trunk, but don't see why it wouldn't work with GDAL >= 1.9. > > > > Tom > > > > From: [email protected] > [mailto:[email protected]] On Behalf Of Rahkonen > Jukka (Tike) > Sent: Monday, June 30, 2014 2:48 PM > To: Tom; [email protected] > Subject: Re: [mapserver-users] OGR/GeoJSON WRITE_BBOX > > > > Hi, > > Perhaps it is your GDAL version that does not write the BBOX for the > collection?
