[mapserver-users] capability to reproject to 2 different projections within the map object of the map file

[Fawcett, David (MPCA)]

I believe that in CGI mode, you can only have one output projection, so your approach won't work.

You can support multiple SRS/projection in WMS mode.  To do this, you put multiple SRS codes in the wms_srs metadata for a layer.

You might be able to change the map projection on the fly by changing the parameters via the URL, I assume that you would also need to change the extent values to match the projection. (I can't verify that map.projection is something that you can change via URL).

If I want all the layers within a map file no matter the layers own projection to have the capability to reproject to 2 different projections would I within the map object of the map file replace:
 PROJECTION
  "init=epsg:4326"
 END

With:
 PROJECTION
  "init=epsg:4326"
  "init=epsg:102113"
  END

Thanks,

John
