Hi Dave,

Did you remember to change the EXTENT in your map file? It needs to be in
metres for Mercator.

Tried using that projection in the top MAP section of the .MAP file, then
put PROJECTION  "AUTO" 
END
In each layer section, strangely now the maps don't show anything.  
When I don't specify any map projection settings, I get it to show in rougly
the correct position just slightly warped..  As soon as I start trying to
change the projections I get nothing.  Sadly I was hoping it was going to be
quite straightforward this problem... :(

Hi Dave,

The list provided me with this projection info a couple weeks ago.  I am
using it successfully to draw mapserv images which overlay on top of Google
maps.

  PROJECTION
    "proj=merc"
    "lat_ts=0.0"
    "lon_0=-90.0"
    "x_0=0.0"
    "y_0=0.0"
    "ellps=GRS80"
    "no_defs"
  END

John
