[Gdal-dev] Re: [kakadu_jpeg2000] Support for GeoJPEG2000 needed

[Julien Demaria]

Greg,

If your need is only to read/write GeoTIFF and GeoJPEG2000 you should use 
this library/utilities : http://www.gdal.org/ (I send a copy of this post 
to the GDAL's mailing list)
It's a "Geospatial Data Abstraction Library" widely used which can 
read/write many (~ 50) raster formats in a same generic way.
GDAL read/write GeoTIFF and has a GeoJPEG2000 driver using the Kakadu 
library which allows to read/write GeoJPEG2000 files.
For example with GAL utilities you can create a GeoJPEG2000 from a GeoTIFF :
gdal_translate -of GTiff geojp2.jp2 geotiff.tif
the inverse operation is :
gdal_translate -of JP2KAK -co "QUALITY=10" geotiff.tif geojp2.jp2     for 
create a GeoJP2 file (with size 10% of the original file) using Kakadu library.

If your really need to implement GeoTIFF geolocation in Kakadu TIFF and JP2 
support, maybe you should also based your work on GDAL library.
But to my mind I think GDAL already do what you want...

Regards,


Julien
