"What we have released is an archive of the HiRISE Experiment Data Records (EDRs) and Reduced Data Records (RDRs). EDRs are in the *.IMG file format and represent individual CCD channels (remember, there are 14 CCDs in the HiRISE camera and two channels per CCD, for a total of 28 channels). These EDRs are cleaned up, calibrated, stitched together, and mapped to Mars’ geometry, resulting in the RDR products. RDRs are in the *.JP2 and *.LBL formats. JPEG2000 is the technology that enables us to offer our gigantic images to the scientific community and the public in a timely and efficient manner. An observation’s image data are in the *.JP2 file and its meta data are in the detached *.LBL files. To view these products, JPEG2000 compatible software is required (see our site for a list of offerings)."

Listed below are images from offered by the Library of Congress Music Division for experimentation. Included are both lossless compression and lossy compression J2K versions of the sample images, with perhaps another variation in having the images sharpened using NIK-Sharpen Pro. The TIFFs are also available to show folks just what a pain it would be do deal with the originals.

The first collection of images comes from the Federal Theatre Project. These images were captured at a high resolution because the source materials were literally disintegrating, and a very good copy was needed. The "LC j2k FedTheatreProj test.pdf" file outlines why digital and JPEG 2000 was the best way to go.

The University of Connecticut Archives & Special Collections at the Thomas J. Dodd Research Center was awarded $40,000 by the Gladys Krieble Delmas Foundation in December 2001 to clean and make accessible a series of hand-written but subsequently water-damaged cards produced by the poet Charles Olson during his effort to transcribe the marginalia in hundreds of books owned by Herman Melville. The renovated cards are scanned at a resolution of 600 DPI, then encoded into JP2 files and bundled with an Encoded Archival Description (EAD) XML box, TEI Lite XML box, and a PDF UUID box. Using Aware's toolkit, the images are delivered to the user's web browser through a server-side transformation to JPEGs.
