I ran 'gdal_translate' and it converted the JP2 image perfectly.<br>
<br>
This is the text it sent to the console:<br>
Input file size is 108, 420<br>
GeoJp2 info found...<br>
<br>
I notice a simularity in the second line gdal_translate's output and
the 'malformed header' apache error.<br>
Snip from Apache error log:<br>
Bad header=GeoJp2 info found...<br>
<br>
Hmmm... I am getting closer. My guess is that the output from the
translation utility is getted slapped to the begining of the header
that is sent to Apache. This would make the header invalid, which in
turn, would cause Apache to choke with the Internal Server Error.<br>

<br>
More insight needed.<br>

The two layer combination is the "new way" of doing tile indexes. I
have tried both the original and the new ways.<br>
<br>
Look at this post: <a class="moz-txt-link-freetext"
href="http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0405/msg00799.html">http://mapserver.gis.umn.edu/data2/wilma/mapserver-users/0405/msg00799.html</a><br>
<br>
After seeing this message in the apache error log...<br>
[Thu Aug 26 02:29:45 2004] [error] [client 192.168.1.101] malformed
header from<br>
script. Bad header=GeoJp2 info found...: /usr/lib/cgi-bin/mapserv421<br>
<br>
... I am wondering if it is an internal Mapserver/GDAL/Apache error. I
looked up "malformed header" on the Apache site.<br>
<a class="moz-txt-link-freetext"
href="http://search.apache.org/index.cgi?query=malformed+header&what=docs1&brief=1&submit=Search%21">http://search.apache.org/index.cgi?query=malformed+header&what=docs1&brief=1&submit=Search%21</a><br>
Result 2 <a href="http://httpd.apache.org/docs/misc/compat_notes.html">Apache
HTTP Server: Notes about Compatibility with NCSA's Server</a> looks to
be the most relevant result.<br>
<br>
This line...<code><br>
exec cgi=""</code> produces reasonable <strong>malformed header</strong>
responses when used to invoke non-CGI scripts.<br>
The NCSA code ignores the missing header (bad idea).<br>
Solution: write CGI to the CGI spec and use <code>include virtual</code>,
or use <code>exec cmd=""</code> instead.<br>
...appears to be somewhat related. I'm not familiar with the
interworkings of Apache, so I'm not sure.<br>
<br>
I feel confident that my syntax is correct. I have beat it to death!
For some reason, gdal-config is telling me that I have JPEG2000
support. I know that it was compiled in. But maybe the way gdal is
calling the JPEG2000 conversion isn't working via the web-server.<br>
<br>
<br>
Any insight?<br>

The 'tile index' layer was created via an ArcGIS extension written by
Mike Juvrud of Mud Labs. What it does is takes the Orthophoto/raster
image from a MrSID format, and chops it up into tiles, outputting the
tiles as TIFF formatted images (max 50MB per image). At the same time,
it generates the 'tile index' layer, filling in the corresponding
filename in an attribute named 'PATH'.<br>
<br>
After verifying this method worked using TIFF files, the 'PATH'
attribute was changed from a .tif extension to a .jp2 extension. So if
I had an image named '104.tif' the new name would be '104.jp2'<br>
<br>
I used the 'jasper' utility to convert the TIFF image to a JPEG2000
using the command: 'jasper -f 104.tif -t tif -F 104.jp2 -T jp2'<br>

</font><br>
</div>
I am trying to tile ortho photos using the JPEG 2000 (jp2) format. I
have created a working tif version.<br>
<br>
I converted the TIF images to JP2 files using jasper. Then I updated
the PATH attribute of the shapefile to reflect the new file extension.
This, however, created unexpected results. I am getting an Internal
Server Error.<br>
<br>
Here is my MapServer output: (mapserv -v)<br>

<br>
Does anybody know if it is possible to use JPEG 2000 instead of TIFF
for this?<br>
<br>
I would like to use this format if possible, as the file sizes are 2-3x
smaller than with the .tif, and the quality differences are
unnoticeable.<br>

Any help/suggestions welcome.<br>
