[mapserver-users] aea projection support?

In order for reprojection to happen in MapServer, you need to specify
both input and output projections in your mapfile.  i.e. you need to
specify the output projection at the top-level in your mapfile, and you
also need to specify the input projection for each layer.

Something to check anyway...
