Ed,
I did what you suggested, and the shoreline displayed fine in UTM extents.

Kevin -
 
Thanks; I'd suggest next modifying the MAP file to comment out ALL 
PROJECTION blocks, and turn off all the layers except the shore line. 
You'll need to adjust the EXTENT to have the right values in UTM 
coordinates, but this should get you a UTM-output map of the shoreline. 
I'm trying to make sure that all your data is valid and is really in the 
projection you think it is.

Ed, 
Yes, it supports proj, and the other layers look okay.  These other layers 
are in the same projection as the map object. 
The custom projection I'm using in the map is as follows: 
# Custom Lambert Conformal Conic 
<50000> +proj=lcc +lat_1=49 +lat_2=63 +lat_0=49 +lon_0=-91.86 +x_0=6200000 
+y_0=2958000 +ellps=GRS80 +datum=NAD83 +units=m +no_defs  no_defs <> 
I've had no problems using this projection with ArcMap. 

I'm running the following: 
Mapserver 4.2 
PHP 4.3.4 
Win2000

Kevin - 
  
Do all your other layers look OK in the output map?  BTW, I think it's 
good practice to include a PROJECTION block in ALL layers if they're not 
all the same projection. 
  
If you run "mapserv -v" from the command line, does it show 
"SUPPORTS=PROJ"?

Hello, 
I'm having trouble with reprojecting in Mapserver.  I'm trying to 
reproject my 'shoreline' file (defined as UTM 17N NAD83) to my map, which 
has been defined with a customized lambert conformal conic projection. 
Based on my Mapfile below, can anyone see why my data will not re-project? 
 Am I missing something?  I thought everything looked okay, but obviously 
something must be wrong!
