Trouble with displaying projected shapefile

[Ethan Alpert]

Do you pass the layer name in the URL (&layers=world_eca)? The status of
your layer is ON this means it's only displayed if requested. Change it
to DEFAULT if you want it displayed regardless of whether you ask for
it. The only other thing I notice is that you pass Decimal Degrees
Extents but say the UNITS are METERS in your mapfile. I'm sure this is
being interpreted wrong. Do a shpdump on the shapfile and use the "File
Bounds" listed as your extents.

shapefile
	
	

	Dear list, 

	I have a shape file, world_eca, projected in "north pole
stereographic". Below are the projection specifications. 

	I added the shape file in the map, but I do not manage to
display it in mapserver. Is there something obvious I am doing wrong?

	An "echo $gpoMap->getProjection()" reveals "+proj=stere
+lat_ts=90 +lat_0=90 +lon_0=0 +k_0=1 +x_0=0 +y_0=0" 

	Regards, 
	Maarten van der Hoeven
