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><br>Liz<br><br><div class="gmail_quote">On Tue, Nov 4, 2008 at 10:13 AM, Lucena, Ivan <span dir="ltr"><<a href="mailto:ivan.lucena@pmldnet.com">ivan.lucena@pmldnet.com</a>></span> wrote:<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>
