No, I'm setting all the parameters (well, as many as I can and understand). I tried to follow the Proj.4 .pdf manual and I was kinda confused what lat_1, lon_1 and lat_2, lon_2 were supposed to be or if I even needed them.
Here is my map file: MAP NAME UniversityOfIllinois STATUS ON SIZE 600 500 IMAGETYPE GIF PROJECTION "proj=utm" "ellps=WGS84" "datum=NAD83" "zone=16" "units=m" "north" END EXTENT 393898 4438945 396253 4441379 #image is 1747 X 1916 pixels UNITS METERS SHAPEPATH "/var/www/mapserver/basic/data/illinois/" IMAGECOLOR 255 255 255 OUTPUTFORMAT NAME thegif DRIVER "GD/GIF" MIMETYPE "image/gif" IMAGEMODE RGB EXTENSION "gif" END WEB IMAGEPATH "/var/www/mapserver/basic/images/" IMAGEURL "/mapserver/basic/images/" END #REFERENCE #IMAGE /var/www/mapserver/basic/data/illinois/colorUofIllinoisGIF.gif # location of the image #EXTENT 393898 4438945 396253 4441379 # extent of the image #STATUS ON # the overview is on by default #COLOR -1 -1 -1 # transparent background #OUTLINECOLOR 255 0 0 # the color of the outline #SIZE 1747 1916 # the size of the image in pixels #END LAYER NAME "UofI" DATA "colorUofIllinoisGIF.gif" TYPE RASTER STATUS ON PROJECTION "proj=utm" "ellps=WGS84" "datum=NAD83" "zone=16" "units=m" "north" END EXTENT 393898 4438945 396253 4441379 CLASS EXPRESSION /*/ COLOR 0 255 0 END END END I have that reference section in there although I really don't know the point behind it. It didn't change a thing, so I commented it out.
