Howard,<br><br>I did try gdalinfo and it works great. Just to be sure, I used gdal_transform to create a tiff file and asked mapserver to try that instead using shp2img, and that worked beautifully. So it's just that the GDAL inside mapserver (??!!)) isn't making the same connection or something. I don't know why. When I do a getfeatureinfo I get that error I mentioned in the first post, but for maps, I just get a segmentation fault.<br>

Liz,<br>
<br>
To use SDE raster data in MapServer, you must use GDAL compiled with SDE raster support. The "native" SDE raster support that was in MapServer was removed and no longer works.<br>
<br>
Ensure that your GDAL SDE raster is working with gdalinfo and then specify your layer as follows:<br>
<br>
<br>
LAYER<br>
<br>
TYPE RASTER<br>
DATA "SDE:<a href="http://sdemachine.iastate.edu" target="_blank">sdemachine.iastate.edu</a>,5151,database,username,password,fully.specified.tablename,RASTER"<br>
...<br>
<br>

I'll give it a try. I didn't actually try it - I read the docs and it didn't suggest that it would support rasters.<br>

Some raster driver in GDAL are not flie based but RDBMS based but most of the softwares based on GDAL did not<br>
noticed that change. In those case, instead of a file path what you need is a identification string but those software<br>
usually have code to grab the file path, to check if the file really exist, to check other files on the same folder and<br>
that is where it crashes.<br>
<br>
What I suggest to Liz is to use a VRT file instead of the identification string. As you might know, a VRT file does not<br>
contain the data but a path to the real data set.<br>
<br>
I use that trick to load images direct from the RDBMS server to OpenEv and QuantumGIS:<br>
<br>
% gdal_translate -of VRT <the identification string of your dataset> <temporary.vrt><br>
... check if it works:<br>
% gdalinfo <temporary.vrt><br>
... check what is inside it:<br>
% more <temporary.vrt><br>
... load it:<br>
% openev <temporary.vrt><br>
% qgis<br>
... click on add layer<br>
... select your <temporary.vrt><br>
<br>
I thought that it would work for mapserve too...<br>
<br>
/filepath/<temporary.vrt><br>
<br>
But Liz tried and said it doesn't. Too bad, I was counting on it. ;(<br>
