Output Data Storage Order

Name Description
ENDIANEndianness of the output bytes

Files: FROM

Description

The cube to be converted to pds format.

Type cube
File Mode input
Filter *.cub

Files: TO

Description

The resulting pds file.

Type filename
File Mode output
Filter *.img

Output Settings: LABTYPE

Description

Changes the type of pds label exported.

Type string
Default STREAM
Option List:
Option Brief Description
STREAMStreams labels dynamically ISIS default, streams the pds labels out to take up as few bytes as possible.
FIXEDExports fixed labels Exports the pds labels in a fixed label format. This fixed size is derived from the number of bytes in each line of the exported cube.

Output Settings: BITTYPE

Description

Bit type of output: 8 bit (0=black, 255=white) 16 bit unsigned (0=black, 65535=white) 16 bit signed (-32767=black, 32768=white) 32 bit (1.17549435e-38=black, 3.40282347e+38=white)

Type string
Default 32BIT
Option List:
Option Brief Description
8BIT8 bit data Pixels are in 8-bit data range (0 to 255).

Exclusions

  • ENDIAN
U16BIT 16 bit unsigned data Pixels are in the 16-bit data range (0 to 65535)
S16BIT 16 bit signed data Pixels are in 16 bit signed data range (-32768 to 32767)
32BIT 32 bit data Pixels are in the 32 bit floating point data range (-3.40282347e+38 to 3.40282347e+38)

Exclusions

  • STRETCH
  • MINPERCENT
  • MAXPERCENT
  • NULL
  • LRS
  • LIS
  • HIS
  • HRS

Output Settings: NULL

Description

If set to true, the minimum value of the raw output data will be reserved for null pixels. The actual value used for null pixels will be denoted in the print.prt file as well as displayed onscreen.

Type boolean
Default true

Output Settings: LRS

Description

If set to true, then an output DN value is set aside for the LRS input pixels. The actual DN value used for LRS pixels will be denoted in the print.prt file as well as displayed onscreen.

Type boolean
Default false

Output Settings: LIS

Description

If set to true, then an output DN value is set aside for the LIS input pixels. The actual DN value used for LIS pixels will be denoted in the print.prt file as well as displayed onscreen.

Type boolean
Default false

Output Settings: HIS

Description

If set to true, then an output DN value is set aside for the HIS input pixels. The actual DN value used for HIS pixels will be denoted in the print.prt file as well as displayed onscreen.

Type boolean
Default false

Output Settings: HRS

Description

If set to true, then an output DN value is set aside for the HRS input pixels. The actual DN value used for HRS pixels will be denoted in the print.prt file as well as displayed onscreen.

Type boolean
Default false

Stretch Options: STRETCH

Description

This parameter is used to select one of three ways to stretch (or map) the input pixels. They are NONE, LINEAR, or MANUAL.

Type string
Default NONE
Option List:
Option Brief Description
NONE No stretch No stretch is performed.

Exclusions

  • MINIMUM
  • MAXIMUM
  • MINPERCENT
  • MAXPERCENT
LINEAR Linear stretch A minimum and maximum are automatically computed based on the statistics of the selected input band. A histogram of the band is used to pick the minimum at 0.5% of the data and the maximum at 99.5% of the data. Input pixels less than or equal to the minimum are stretched to black while pixels greater than the or equal to the maximum are stretched to white. A linear mapping occurs between the minimum and maximum.

Exclusions

  • MINIMUM
  • MAXIMUM
MANUAL Manual stretch This option allows you to pick your own stretch. You must enter a value for MINIMUM and MAXIMUM input pixel.

Exclusions

  • MINPERCENT
  • MAXPERCENT

Inclusions

  • MINIMUM
  • MAXIMUM

Stretch Options: MINIMUM

Description

The minimum input pixel value which will be mapped to black.

Type double
Less Than
  • MAXIMUM

Stretch Options: MAXIMUM

Description

The maximum input pixel value which will be mapped to white.

Type double
Greater Than
  • MINIMUM

Stretch Options: MINPERCENT

Description

The percentage of data in the histogram used to compute the minimum pixel value in the stretch.

Type double
Default 0.5
Less Than
  • MAXPERCENT

Stretch Options: MAXPERCENT

Description

The percentage of data in the histogram used to compute the maximum pixel value in the stretch.

Type double
Default 99.5
Greater Than
  • MINPERCENT

Output Data Storage Order: ENDIAN

Description

This parameter is used to select one whether the output will be streamed starting with the most significant byte (MSB) or starting with the least significant bytes (LSB). The choice should be made by the user depending upon the format read by the system architecture from which they plan to read the raw data.

Type string
Default LSB
Option List:
Option Brief Description
LSBLeast significant byte The least significant byte will be the first byte output.
MSBMost significant byte The most significant byte will be the first byte output.

History

Noah Hilt2008-05-20 Original version
Christopher Austin2008-08-07 Added the Label Type capability (param)
Kristin Berry2014-06-06 Changed to assume that radii without units in the input Isis cube are in meters, map scales without units are in meters/pixel, and map resolutions without units are in pixels/degree.
