JPEG 2000 format instead of TIFF for a RASTER layer

Brant -
 
You mentioned "tile", so I assume you're using a TILEINDEX.  You mention
changing the PATH attribute of the shapefile - could you be a little
more specific?  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 new shapefile.

Subject: [UMN_MAPSERVER-USERS] JPEG 2000 format instead of TIFF for a
RASTER layer


I am trying to tile ortho photos using the JPEG 2000 (jp2) format. I
have created a working tif version.

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.

Here is my MapServer output: (mapserv -v)
MapServer version 4.2.2 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF
SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER INPUT=EPPL7
INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

Here is my gdal-config output: (gdal-config --formats)
gxf gtiff hfa aigrid aaigrid ceos ceos2 iso8211 xpm sdts raw dted mem
jdem envisat elas fit vrt usgsdem l1b nitf bmp pcidsk bsb jpeg2000 gif
jpeg png grass


Does anybody know if it is possible to use JPEG 2000 instead of TIFF for
this?

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.

Any help/suggestions welcome.


Thank you,

Brant Anderson
