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
