[Mapserver-users] Tutorial raster examples on Mapserver 4.0?

[Ann Keane]

Maybe you can see what I'm missing.  I compiled MS3.5 and the original 
example works.  Under MS4.0, all I get is an empty png image.  Here's 
what I've got for MS4.0.


The map file for ms4.0 is:


NAME S2EX2
EXTENT -97.5 41.619778 -82.122902 49.38562
SIZE 400 300
SHAPEPATH ""

LAYER # Shaded Relief Raster
   NAME "relief"
   DATA 
"/httpd/www/programs/2003/neaqs/tutorial35/data/raster/shdrlfi020g_ugl.tif"
  # STATUS DEFAULT  # default does not work
STATUS ON
   TYPE RASTER
   END

END # end of map file


gdalinfo returns:

Driver: GTiff/GeoTIFF

Coordinate System is `'
Origin = (-98.607616,49.868450)

I've also tried:
