The emerging international standard for image compression and decompression that is ommonly known as JPEG 2000 (JP2) has already been adopted by such players as BAESystems, General Dynamics, International Land Systems, LizardTech, LuraTech, and orthrup Grumman as an efficient means of handling large imagery collections. And,thanks to input from a variety of industry experts, the standard is not just a more tightly ompressed version of the familiar JPEG image: its 14 parts also include designs thatsupport secure military radio transmissions, regional decoding, inclusion of GML Geography Markup Language) for geographic coordinates and object descriptions, andpredefined resampling for rapid viewing at different scales. Tuning a JPEG 2000 image ile's encodings to match a specific workflow can improve rendering performance evenwhen that file is very large.
