[NEWBIE] Using Mapserver and PROJECTION

[François TOURDE]

Hi the list.

I'm a newbie using mapserver, and in geodata. :( ... I've a probably
simple problem using the image output:

On my .MAP file, I have the following lines:

# Mode latlong  
  EXTENT 2.8830 42.683 7.5 43.950 # Geographic
  PROJECTION "init=epsg:4326" END
  UNITS DD

All my layers have no PROJECTION infos.

When I replace the above lines by:

# mode Collignon
  EXTENT 205512.50       4889370.83 521106.75       5051672.48
  PROJECTION
   "proj=collg"
  END
  UNITS METERS

the image is ... blank. No coast lines, no features, etc...

Could you point me the problem?

Thanks in advance.
