[mapserver-users] displaying 3-band images

[Brent Fraser]

David,

    It sounds like image registration / coordinate system definition 
problem.  While it is not necessary for the image to have a coordinate 
system defined (e.g as a geotiff tag) sine you can specify it in the 
LAYER portion of the map file, I think it does need image registration 
information, either as geotiff tags or in a .tfw (or .wld) file.  
Specifying the EXTENT in the map file is only a layer "hint" to 
mapserver, it does not specify the image registration.

   I could be wrong; mayby there have been enhancements to use the 
EXTENT or METADATA information.

What are your parameters for EPSG:43001?

Best Regards,
Brent Fraser
