ISIS 3 Application Documentation
Import PDS formatted Kaguya Multiband Imager (MI) image into Isis format
Description
This program will import a PDS formatted Kaguya MI VIS and NIR level 1 (EDR)
image into an Isis cube.
The user is given the option to specify incoming special pixel
values in the PDS file so that they can be assigned equivalent values for special pixels
in ISIS3. The order of precedence for special pixels in ISIS3 from highest to
lowest priority is the following:
-
NULL
-
HRS
-
LRS
-
HIS
-
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 user should note that the Kaguya MI data files will most likely contain
a SCALING_FACTOR that is not equal to 1.0. The SCALING_FACTOR is used to scale
the pixel values in the PDS file before they are imported to the ISIS file.
Before the scaling is done on the pixel values, the special pixel conversions
will be applied first. After the special pixel conversions are done, then the
scaling factor is applied to those pixels that don't have special pixel values.
As a result, you may get results that you weren't expecting.

At this time, there is no camera model for the Kaguya MI data. In order to
be able to perform photometry on the Kaguya MI data, the SubSolarLongitude
and SubSolarLatitude information needed to be calculated. These calculations
are done by using the aaplus library developed by P J Naughter at
http://www.naughter.com. This library can only be distributed in binary form,
so it has to stay in the local directory of ISIS where it will not be
distributed. The formulae used to do the calculations were taken from Meeus
"Astronomical Algorithms" (1st Ed). This code can be removed as soon as a camera
model is available for the Kaguya MI camera. The start and stop times for these
images are very close, so the start time is used to calculate the SubSolar lat/lon
information.

Application category name changed from Import and Export to Kaguya. Fixes mantis ticket #951.
|
| Janet Barrett | 2013-06-13 |
Fixed code so that it sets the NaifFrameCode appropriately according to the base band specified
in the labels. Fixes mantis tickets #1167 and #1680.
|
| Janet Barrett | 2014-02-10 |
Added parameters (SETNULLRANGE, SETHRSRANGE, SETHISRANGE, ETLRSRANGE, SETLISRANGE)
to allow the user to specify special pixel values. Fixes #2033.
|
| Adam Paqeutte | 2016-08-04 |
Added a new error message informing the user that the file they are using is not compatible with
kaguyami2isis. Fixes #2358.

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.

Special Pixels:
NULLMIN
Description
Minimum pixel value to set to NULL. All values greater than or equal to
NULLMIN and less than or equal to NULLMAX are converted to NULL.
Special Pixels:
NULLMAX
Description
Maximum pixel value to set to NULL. All values greater than or equal to
NULLMIN and less than or equal to NULLMAX are converted to NULL.
Special Pixels:
SETHRSRANGE
Description
If this option is set to "yes" or "true", a range of input raw pixels
defined by the HRSMIN and HRSMAX parameters are converted to HRS
pixels. 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"
