Import PDS or ISIS2 image into ISIS3 cube format

Description

This program converts a PDS or ISIS2 formatted file to an ISIS3 cube format. The standard PDS image is defined in the "FROM" parameter, and not the "IMAGE" parameter. If the PDS file has a detached label file and an image file, both are required to exist in the working directory. If the label is detached, the detached label filename is defined as the input file for the "FROM" parameter. The "IMAGE" parameter does not need to be defined, unless the program fails to find the image file specifed in the label file upon the program's execution. The default settings normally work for most PDS products, but occasionally the user may need to modify the default values in order to obtain an image that meets their specific requirements.

The incoming special pixel values in the PDS file are assigned equivalent values for special pixels in ISIS3. The order of precedence for special pixels in ISIS from highest to lowest priority is the following:

  1. NULL
  2. HRS
  3. LRS
  4. HIS
  5. LIS
If any incoming pixel value falls within two different special pixel types, the special pixel with the higher priority is assigned. The user may also specify a range of pixel values to be assigned to the different special pixels. If the range of pixel values defined by the user for the different special pixels overlap, the special pixel with the highest priority is assigned. For example, if NULLMIN=0.0, NULLMAX=3.0, LISMIN=3.0, and LISMAX=5.0, the actual raw value 3.0 can be assigned as a NULL or LIS, but is translated to NULL because NULL has a higher priority than LIS. The conversion of images from ISIS2 to ISIS3 follows the same rules as PDS images, except that the label information is propagated to the output file.

The best option to convert files from ISIS2 to ISIS3 is to maintain all the input file settings, and do not change the bit type or change any incoming pixel values to special pixels. When an ISIS2 Level1 image is imported into ISIS3, it is important to note the label information is not propagated from the ISIS2 to the ISIS3 cube file. For an ISIS2 Level2 image or mosaic file, a limited set of label information is transferred to the ISIS3 labels that include the "Instrument," "BandBin," and "Mapping" groups.

Files: FROM

Description

Specify a PDS file, PDS label file, or ISIS2 cube file. If the input file is a PDS detached label file and the companion image file is not in the same directory, use the parameter "IMAGE" to define the location and filename of the image, otherwise just enter the label file name.

Use this parameter to specify the output cube filename.

Special Pixels: SETNULLRANGE

Description

If this option is set to "yes" or "true", a range of input raw pixels defined by the NULLMIN and NULLMAX parameters are converted to NULL pixels. All other valid pixels that do not fall within the ranges specified for LIS, LRS, HIS, and HRS pixels are transferred to the output file unchanged. If the bit type of the input file is changed, the NULL and HRS special pixels may be incorrectly set to valid pixel values. For example, if a raw 8-bit file is output to 16 or 32-bit, the pixel values "0" and "255" may be converted to actual values instead of retaining the special pixel property. If the output file remains as 8-bit, then "0" stays as NULL and "255" stays as HRS.

All other valid pixels that do not fall within the ranges specified for LIS, LRS, HIS, and NULL pixels are transferred to the output file unchanged. If the bit type of the input file is changed, the NULL and HRS special pixels may be incorrectly set to valid pixel values. For example, if a raw 8-bit file is output to 16 or 32-bit, the pixel values "0" and "255" may be converted to actual values instead of retaining the special pixel property. If the output file remains as 8-bit, then "0" stays as NULL and "255" stays as HRS.
