GeoJasper is a free and open source geo supporting extension for JPEG2000 JasPer library
GeoJasper is a free and open source geo supporting extension for JPEG2000 JasPer library and a command line transcoder. It converts images between GeoTiff and GeoJp2™ (GeoJpeg2000) correctly preserving all geo information, like "geotifcp" tool. GeoJasper supports 8, 12, 16 and 32 bit channels, supports images with more than 4 channels, striped as well as tiled images for reading and writing and also images geo-referenced through World Files (TFW). Moreover, it may combine three 1 band TIFFs into one RGB image. Also, it can print geo data without decoding the whole JPEG2000 image showing it exactly like "listgeo" application, including projection information and lat/long for tie points (example). Recently XMP tag support was added, it allows seamlessly transfer XMP tag between jpeg2000 and TIFF images.
