Description
8BIT
8-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)
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.
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.
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.
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.
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.
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.
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
LSB
Least significant byte
The least significant byte will be the first byte output.
MSB
Most significant byte
The most significant byte will be the first byte output.
This parameter allows the user to specify the value of the standard
PDS keyword NOTE within the output PDS label. This keyword
will be located in the Root of the PDS PVL label.
This example shows a typical conversion of an Isis 3 Lunar
Orbiter cube to a PDS format image. The default settings
produce 32-bit data with least significant byte first order.
Command Line
lopdsgen
from=lev1.cub to=lev1.pds.img
In this example, lopdsgen will convert a cube to a pds
format image with all settings left at their defaults.

cube to a PDS image.
Input Image
lev1.cub
Input cube for lopdsgen
Parameter Name:
FROM
This is an Isis 3 cube, specifically a level 1 LO product, that
will be exported to a standard PDS format image.
