[mapserver-dev] variable substitution for projection

[Lime, Steve D (DNR)]

Zach: You should be able to change the projection through the URL like so:

  ...&map.projection=EPSG:3158&...

No need to runtime subs...

Subject: [mapserver-dev] variable substitution for projection

ok i am working with mapserver and a nodejs project and so i am calling mapserver like so.

mapserv -nh "/getPreviewImg.map&mode=map&mapext='+req.params.extent+'&filename='+req.params.imgname+'&projection=3158"

the issue is that mapserver dose not support projection based run time substitution and so i was wondering if that is possible to add and how hard it would be (maybe i could to it myself etc if pointed in right direction because i have no experience with mapserver's src)

map file example thats what i want to replace

PROJECTION
    "init=epsg:%projection%"
END

or perhaps even this then i could build what ever

PROJECTION
    %projection%
END
