Since your units are in FEET, you need to use the to_meter parameter.

    proj=lcc 
    lat_1=39.933333333 
    lat_2=40.800000000 
    lat_0=39.333333333 
    lon_0=-77.750000000 
    x_0=609601.219 
    y_0=0.000 
    ellps=clrk66 
    datum=NAD27 
    to_meter=0.3048006096 
    no_defs

Hi List,

          I am having the problem with my raster image display. Does any one
can help me what is wrong in my projection definetion.  When i load this
raster image using ARCMAP its showing in the PA exact place.

 These are my projection definitions.

 Map level projection definition

          PROJECTION
                    "proj=poly"
                    "ellps=GRS80"
                    "lon_0=77.75w"
                   "lat_0=40.925n"
                   "units=m"   
          END
          
Layer definition

	   LAYER
	   NAME "I99-07"   
	   TYPE raster
	   DATA "I99-07.tif" 
	   STATUS default
	   PROJECTION
                  "proj=lcc"
                  "lat_1=39.933333333"
                  "lat_2=-77.750000000"
                  "lat_0=39.333333333"
                  "lon_0=40.800000000"
                  "x_0=609601.219"
                  "y_0=0.000"
                  "ellps=clrk66"
                 "datum=NAD27"
                 "units=m"
                 "no_defs"
               END
	 END # LAYER
  
 The Projection definition for the raster layer is  Pennsylvania South
NAD27  Feet.    

I am using Apache web server, Windows 2000 and  

MapServer version 3.6.0 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
SUPPORTS=PROJ SUPPORTS=TTF SUPPORTS=WMS_SERVER 
SUPPORTS=WMS_CLIENT INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR INPUT=GDAL
INPUT=SHAPEFILE

Thanks for your help.
