[Mapserver-users] Problem w/ 8-bit TIF & Mapserver 3.3

[Gregory S. Williamson]

How are you setting the layer to "ON" ? Perhaps that's the problem ?

I use very similar setup (mapserver 3.6) with large (45m meg) 8 bit TIFFs and it works fine with the defailt projection for the map:
LAYER 
  NAME "sf_doqq"
  DATA "o37122f3nw.tiff"
  TYPE RASTER
  STATUS ON
END

Hello,
 I've been working on getting mapserver to render a set of high-resolution 
aerial photos. The images are in .tif format, unsigned 8-bit with an 
associated .tfw file. We are currently using Mapserver v3.3. For testing 
purposes we are trying to get just a single image to work but here is the 
problem.... Mapserver doesn't return an image (in map mode) when the layer is 
added. Here is the mapfile entry ->

LAYER # Aerial test
	NAME "aerial"
        DATA ./aerial/nov01_utm/rm94g_wv.tif
	STATUS OFF
	TYPE RASTER
END

The file size of the test photo is 15.4 MB which shouldn't be a problem since 
we're successfully using a 30 MB tif w/ mapserver. The paths are correct 
(other tifs in the same directory work). The image is 8-bit and displays 
perfectly in other GIS/RS software.

Is there any thing I'm forgetting? Is there some minor variation in the .tif 
format that could be causing this? Has anyone run into this before??

I'll have access to the mapserver error log tomorrow... is there anything I 
should look for?

Thanks for the help, guys.
