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>
<br>
Here is the output from ogrinfo of a TIFF version, and another of the
JPEG2000 version.<br>

Could you post the LAYER definition in your MAP file for this layer? I
would expect that you would use gdaltindex to create a new TILEINDEX
shapefile with the new filenames in it (remember that gdaltindex will
add to an existing file, so you'll want to create a new one). Then you
would change the TILEINDEX statement in your MAP file to refer to this

<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>
