No reprojection done

[Ed McNierney]

Luiz  & Bengt -
 
I would expect that if Bengt is working with maps of Scandinavian
countries, the difference between Plat Carree and Mercator should be
noticeable (Mercator will "stretch" things north/south by quite a bit
compared to a "geographic" or Plat Carree projection).
 
Bengt, are you sure you have a good PROJ installation and that MapServer
is compiled with PROJ support (run mapserv -v and look for
"SUPPORTS=PROJ")?

Well, 

   it seems that there no perceptual changes each other:

# World Mercator
<54004> +proj=merc +lat_ts=0 +lon_0=0 +k=1.000000 +x_0=0 +y_0=0
+ellps=WGS84 +datum=WGS84 +units=m  no_defs <>

# World Plate Carree
<54001> +ellps=WGS84 +datum=WGS84 +units=m  no_defs <>
# World Equidistant Cylindrical
<54002> +ellps=WGS84 +datum=WGS84 +units=m  no_defs <>

# WGS 84
<4326> +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs  no_defs <>

	Hi,
	I've set up a WMS server with an initial singe layer to test
reprojection. However , I can't get the projection to work. Whatever
output projection i try I get the same geographical (4326) back. For
example, when I make a WMS request  with  SRS=EPSG:54004 (Mercator) and
bounding box in that projection I get an 4326-map back. I do not get any
errors. Here is my map-file: 
	
	MAP
	NAME WMS-test
	STATUS ON
	SHAPEPATH "shp"
	IMAGECOLOR 255 255 255
	FONTSET ../etc/fontset.txt

	    "wms_srs"       "epsg:9823 epsg:4326 epsg:54004"
	  END
	END
	
	PROJECTION

	END

	  DATA 'the_geom from k92_strandlin_polygon'
	  PROJECTION
	   "init=epsg:4326"
	  END
	  CLASS
	    NAME "strandlin-pgx"
	    COLOR 255 251 237
	    OUTLINECOLOR 100 100 100
	  END 
	END
	
	END
