Not sure though if MapServer should be supporting any projection other than urn:ogc:def:crs:OGC::CRS84 as per the formal GeoJSON specification https://tools.ietf.org/html/rfc7946.

I will try and update that. Might be worth thininking about supporting runtime subs in the OGR url to pass extent values easily - where MapServer does the substitution using computed values. Kinda like the bbox hack for PostGIS. ________________________________ From: James Klassen <[email protected]> Sent: Friday, December 7, 2018 10:50:36 AM To: Lime, Steve D (MNIT) Cc: [email protected] Subject: Re: [mapserver-users] OGR GeoJSON Layers...
