[mapserver-dev] variable substitution for projection

Syntax will be a little different since it's not a top-level object, try:

  ...& map.layer[layername]=PROJECTION+EPSG:3158+END&...

That syntax would probably work for the map.projection method too (the PROJECTION/END should be stripped off).

that seem's to have done the trick sort of now i am just wondering if i can set that for a specific layer i tried


but that did not seem to work. Setting the map projection will probably be fine for our project at least for now.

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


or perhaps even this then i could build what ever
