[mapserver-users] Raster layer problem

[Brent Fraser]

Carl,

   Mapserver is likely trying to use it's native tif driver to open the 
file and not finding the georeferencing information in the .tab file (it 
doesn't know anything about .tab files).    Mapserver can use GDAL to 
access raster data, and I think GDAL can get the georeferencing info 
from a  .tab file, but I don't know of any way to force Mapserver to use 
the GDAL driver for tif files.  Maybe if you renamed the .tif to .tiff 
(and change the string in the .tab file).  Interesting problem....

One work-around would be to convert the tif/tab to geofiff (see 
http://www.gisnotes.com/wordpress/2007/06/processing-mapinfo-raster-jpeg-images-using-gdal/)

Best Regards,
Brent Fraser
