plancd - Read JPL archive CD files and write to disk PLANCD reads a CD-ROM file containing image files in the JPL (Jet Propulsion Laboratory) VICAR (Video Image Communication And Retrieval) label format as defined in JPL PUBLICATION 85-50. These CD-ROMs were created from archive tapes containing VOYAGER, VIKING, MARINER9 and MARINER10 images. The input file may come either directly from the CD-ROM or a disk file that was copied from the CD-ROM. PLANCD produces ISIS image labels and writes labels and image to an ISIS cube file. PLANCD is designed to read archive CD's of VOYAGER, VIKING, MARINER 9 and 10 missions. VIKING images have a special processing "feature". It was discovered that when VIKING images were being written to tape and a dropped line was encountered, the dropped image line was inadvertently replaced with the 16th previous image line. PLANCD incorporates an algorithm to drop these lines and replace them with NULL values. As a result, dark lines will appear across the width of the image. The lines may be filled by applying a combination of filters to the image. PLANCD will list the number of lines dropped at the end of the program, and the session log file will contain a line by line account of lines that are dropped. This process is only used if MISSION=VIKING. Programmer: Tracie Sucharski, U.S.G.S., Flagstaff, AZ

ADDITIONAL NOTES:
Parm | Description |
---|---|
FROM | CD-ROM file which is being read from the CD-ROM or a disk file which was copied from the CD-ROM+. |
CDID | Identification name or number for the CD-ROM. CDID value cannot exceed 16 characters in length. The CDID is simply listed in the session log file. PLANCD does not check the validity of the CDID. |
TO | Output cube file name. If the file extension is omitted, then ".cub" will be assumed. |
MISSION | The mission from which the data is collected. There are only four missions that PLANCD will process at this time. They are: VIKING VOYAGER MARINER9 MARINER10. Each of these missions has been archived by JPL to a 6250 bpi tape library. Each mission has its own tape format. Each image for the missions is stored in an output format called VICAR standard format experiment data record (VSFEDR). These tapes were then archived on CD-ROM. The VICAR format was developed by JPL's image processing laboratory. See JPL publication 85-50 for more information. |
OTYPE | Output pixel data type. Permitted values are: NULL - output type is same as input file pixel type 1 - 8-bit (integer with type conversion parameters) 2 - 16-bit (integer with type conversion parameters) 3 - 32-bit (floating point) |
USERNOTE | Comment from the user. This will be recorded in the ISIS session log file and also in the History entry that is put into the History object of the output file. |
