[mapserver-users] IIS and mapfiles and also GDAL

[Brent Fraser]

Chris,

   If you have a current version of Mapserver (v5,v6?), then should be 
GDAL compiled in.  The GDAL library needs to find projection definition 
files so I usually include the following in all my map files:

     CONFIG "PROJ_LIB" "\ms4w\proj\nad"
     CONFIG "GDAL_DATA" "\ms4w\gdaldata"

Another potential problem you may be having  is with EPSG:900913.  It is 
not included in GDAL/PROJ's epsg file so I add the following to 
\ms4w\proj\nad\epsg:

<900913> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 
+x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs <>

Best Regards,
Brent Fraser
