Description 

    Themis image cleanup procedure developed for the Mars geologic base
    map production and the ancillary datasets.  The RDR's or radiometrically
    calibrated images are required as input to the program.  The 12.57um
    wavelength band is selected for the mosaic, and the 14.88um atmosphere
    band is used as input to "thmdriftcor" program.  The following programs
    are run:
        thm2isis - converts to isis format
	spiceinit - updates SPICE information
	camstats - collects camera staistics
	thmdriftcor - applies atmosphere correction using 14.88um band
	cosi - applies a basic photometric normalization using the incidence
	     angles for improved tone matching
	cubenorm - used to cleanup banding(column) effect on the RDRs
	lineeq - normalize base on line averages for signal drifts and/or
	     correcting for photometric changes during crossover from day to
	     night.
	findgaps - find gaps in the input image
        Generate statistics file and footprint information for input into GIS
	     packages

    The InstrumentId must be "THEMIS," DETECTOR_ID must be "IR,"
    BandBinCenter must have "12.57um," and "14.88um" for the
    atmospheric correction.

    If NIGHT is checked then the night time IR images are processed, and
    the incidence angle test is not performed.

    The spiceinit program will automatically use nadir pointing if it fails
    to update with reconstructed or predicted ck kernels.

    If RMINPUT is checked then the input file is deleted after processing.

    If RMHIGHINC is checked then the input RDR file is deleted from
    processing if the incidence angle test is not meant.

Files: FROMLIST

Description

List containing input filenames. The input files in this list need to be calibrated PDS formatted Themis RDR.

Type filename
File Mode input
Filter *.lis *.lst

Files: TOPATH

Description

Output file pathname. All output files will be written to this directory.

Type string
Default None

Processing Options: NIGHT

Description

If checked, this option will process a night time image. For night images the program cosi will be skipped.

Type boolean
Default FALSE

Processing Options: ATMOSCORR

Description

Do not perform the atmospheric correction with thmdriftcorr. The step will be skipped.

Type boolean
Default FALSE

Output Information for input into GIS Software package: INFO

Description

A selected subset of camera statistics information required for the geologic map bases are output for import into a spreadsheet.

Type boolean
Default FALSE
Inclusions
  • TOSTAT
  • FOOTPRINT

Output Information for input into GIS Software package: TOSTAT

Description

This is the output filename that will contain the camera statistics information for import into a spreadsheet.

Type filename
File Mode output
Default None
Filter *.txt *.TXT

Output Information for input into GIS Software package: FOOTPRINT

Description

A footprint polygon information will be output for input into a GIS program. This is normally required for the geologic base map packages, but not needed if the files will not be imported into a GIS package.

Type boolean
Default TRUE

File cleanup and reporting Option: RMINPUT

Description

If selected, delete input files after processing is completed.

Type boolean
Default FALSE

File cleanup and reporting Option: RMHIGHINC

Description

If selected, delete input files that have a minimum incidence angle greater than 90 degrees.

Type boolean
Default FALSE
Inclusions
  • HIGHINCLIST

File cleanup and reporting Option: HIGHINCLIST

Description

Output list file that will contain the names of files that were deleted because of their high incidence angles.

Type filename
File Mode output
Default None
Filter *.lis *.lst

File cleanup and reporting Option: NOFILELIST

Description

Output list file that will contain the names of files that do not have matching RDR files for the EDR files.

Type filename
File Mode output
Default None
Filter *.lis *.lst

File cleanup and reporting Option: NADIRSPCLIST

Description

Output list file that will contain the names of files that have only Nadir pointing available to them.

Type filename
File Mode output
Default None
Filter *.lis *.lst

File cleanup and reporting Option: IMAGEGAPLIST

Description
