Okay.<br>
<br>
This time I compiled 'jasper' without the geo referencing 'geojasper'
so now I am using plain Jasper.<br>
I then compiled GDAL with the new ungeofied (GeoJP2=no) Jasper library.<br>
<br>
Then I tried to view my map. The server didn't give an Internal Server
Error this time! But a new problem is here. The images just don't show
up. I viewed the JPEG2000 images with "Image Viewer 2" in Windows, and
they appear just fine, so I know they are supposed to be there. The
layer used for tiling uses the same shapes as the TIFF version did, so
the Extent values should be proper.<br>
<br>
Next I compiled a new Mapserver. Wondering if the new GDAL needs to be
reflected in the Mapserver compilation.<br>
Then I tried to view my map again. The orthophotos still are not there.<br>
<br>
Is there a way to display an image using Mapserver without using an
extent, just to test if Mapserver is displaying the graphic at all? I
would like to know if the image is not being processed correctly, or if
it is just out of the viewport of my map. I did zoom out aways, to see
if the images were near by, but no such luck.<br>
<br>
Thanks,<br>
Brant<br>

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>
<br>
More insight needed.<br>
<br>
Thanks,<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"

After seeing this message in the apache error log...<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>

<b>Subject:</b> [UMN_MAPSERVER-USERS] JPEG 2000 format
instead of TIFF for a RASTER layer<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>
MapServer version 4.2.2 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF
SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER INPUT=EPPL7
INPUT=OGR <b>INPUT=GDAL</b> INPUT=SHAPEFILE<br>
<br>
Here is my gdal-config output: (gdal-config --formats)<br>
gxf gtiff hfa aigrid aaigrid ceos ceos2 iso8211 xpm sdts raw dted mem
jdem envisat elas fit vrt usgsdem l1b nitf bmp pcidsk bsb <b>jpeg2000</b>
gif jpeg png grass<br>
<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>
<br>
Any help/suggestions welcome.<br>
<br>
<br>
Thank you,<br>
<br>
