This page describes and points to software that provides display and processing capabilities for the Clementine data archived on the CD-ROM set and available in NRL Clementine WWW site. The software is listed below by platform. Below that is an overview of the software's functionality. The individuals supporting this web site have limited experience with the software and consequently can not offer too much advice with regard to it's use.

The PCDOS, MAC and SUNOS software can be used to decompress the Clementine raw images. CLEMDCMP will decompress the raw image and output it into one of four formats:
The source code is provided for each platform. Instructions on how to install and run the software is in the file CLEMDCMP.TXT.
Because the image decompression program, CLEMDCMP, requires a Discrete Cosine Transform (DCT) it may take several minutes to decompress an image on hardware platforms with slow processors. For example, in tests on a Macintosh IIci, the decompression takes approximately 4 minutes. CLEMDCMP has been tested on hardware platforms with modern processors, such as an Intel 486DX2/66-Mhz, and the decompression takes just several seconds.
CLIMDISP is an image display and processing program. It can be used to display Clementine uncompressed images and histograms. See CLIMDISP.TXT for instructions on how to install and run the program.
Note: CLIMDISP currently can not create GIF formatted files for the Clementine images. Additionally, it can not read the version of GIF files created by the Clementine Decompression (CLEMDCMP) program which is also included on the Clementine EDR Archive CD-ROMs. If you wish to display Clementine images with CLIMDISP, generate a PDS format image file when decompressing with CLEMDCMP.
A special version of NIH Image, found in the MAC/BIN subdirectory, will display PDS decompressed Clementine images. This program is stored in a Stuffit file which is in BinHex format. See IMAGE.TXT in the DOC for instructions on how to install and run the program.
The Clementine EDR image files use the PDS label constructs
RECORD_TYPE = "UNK", and ^IMAGE = xxxxx
XV is a shareware program for displaying images. XV was written by John Bradley of the University of Pennsylvania. It is in a compressed tar file. See XV.TXT for instructions on how to decompress and untar this file. XV will not display PDS labeled files, but will display TIF and GIF formatted files.
The XV software, for image display on a sun/unix environment, is not able to read the Clementine PDS labeled files. If you intend to use XV as the display system for the Clementine data products, output GIF or TIFF images with the CLEMDCMP program.
