[mapserver-users] .map file wont display in Open Layers

Wed Jul 15 00:29:03 PDT 2009

Thanks for your reply.

I have set up the IMAGEPATH and IMAGE URL as you have suggested and i can now view the outline of my map however it is in red. As you suggested is is probably my projection which i causing this. Any ideas what the correct projection setting might be?

Thanks again

Paul
