thmproc

Runs Mars Odyssey Themis images through the applications necessary to create a map projected product. There are two stages of processing, ingestion and mapping (radiometric calibration is assumed as Themis RDRs are available). Each stage can be disabled and runs all the programs necessary to complete that stage if not disabled.

All intermediate files will be generated in the users Isis temporary directory and deleted after they are no longer needed. In case of a catastrophic failure the intermediate files should be deleted. Their names will be the name of the application appended to the original file name followed by a 6 digit unique number.

Description

Input filename. This file can be in one of two stages. A raw PDS Themis RDR or an ISIS Level 0/1 cube. The level 0/1 cube is assumed to have been run through thm2isis and spiceinit.

Type	filename
File Mode	input
Filter	*.QUB *.imq *.img *.cub

Description

Output filename from the last enabled processing sequence. By default the filename will be generated from the input filename with ".lev#" appended to the name, where "#" is the last level of processing (i.e., INGESTION = "lev1" or MAPPING = "lev2"). For ThemisVIS images, if processing is stopped at the ingestion phase, there will be an output cube for each frame in the image, with a ".frame#" appended to the end of the filename.

Type	cube
File Mode	output
Internal Default	Automatic

Description

This parameter allows the user to specify a sub-set of bands to process. Enter bands separated by commas (no spaces allowed). For example, 1,3,8 or 1-3,9 or 5

Type	string
Internal Default	All

Description

This option allows the user to decide whether the intermediate files created in the thmproc application are to be deleted. The default value is TRUE.

Type	boolean
Default	TRUE

Description

Process the input file through all steps. This includes "thm2isis" and "spiceinit"

Type	boolean
Default	YES
Inclusions	PCK CK SPK SHAPE CKNADIR

Description

Process the input file through level2. This includes cam2map.

Type	boolean
Default	YES
Inclusions	MAP PIXRES

Description

Naif kernel file to be used for the target attitude and shape.

Type	filename
File Mode	input
Default Path	$BASE/kernels/pck/
Internal Default	none
Inclusions	INGESTION

Description

Naif kernel file to be used for the spacecraft pointing.

Type	filename
File Mode	input
Default Path	$odyssey/kernels/ck/
Internal Default	none
Inclusions	INGESTION

Description

Naif kernel file to be used for the spacecraft position.

Type	filename
File Mode	input
Default Path	$odyessy/kernels/spk/
Internal Default	none
Inclusions	INGESTION

Description

Compute nadir pointing if no other kernels exist

Type	boolean
Default	false

Description

ISIS camera models can use a shape model (a projected ISIS cube that defines the radii for a global or regional area). You can choose to select a shape model or to use the definition of the ellipsoid found in the planetary constants (PCK) file.

Type	string
Default	SYSTEM
Option List:	Option Brief Description ELLIPSOID Use triiaxial ellipsoid from PCK The camera will use the radii defined in the planetary constants file (PCK) when determining intersections of the body surface Exclusions MODEL SYSTEM Search system for a default shape model This option will search the default system data area ($ISIS3DATA/base/dems) for a shape model that matches the target of the input cube. If none are found then no shape model will be used and the default ellipsoid parameters found in the planetary constants (PCK) file define the shape. Exclusions MODEL USER User specified shape model file The camera will use shape model defined by the parameter MODEL
Inclusions	INGESTION

Description

A map projected ISIS cube which contains the radii of the target. The file can cover more than the input cube (FROM) but must minimally cover the data in the input cube.

Type	cube
File Mode	input
Default Path	$base//dems/
Filter	*.cub

Description

A file containing the desired output mapping parameters in PVL form. This file can be a simple hand produced label file. It can also be an existing cube label which contains a Mapping group.

Type	filename
Internal Default	Sinusoidal
Inclusions	MAPPING
Filter	*.map

Description

Specifies the resolution in meters per pixel. If not in the MAP file the resolution will be computed from the themis level 1 cube.

Type	double
Internal Default	Automatic
Minimum	0.0 (exclusive)
Inclusions	MAPPING

Description

thmvistrim removes the overlap between framelets, which often contains both valid and invalid data. Set this to false to preserve this data. thmvisflat applies a flat-field correction to the data.

Type	boolean
Default	true

This program will process this themis edr from ingestion to mapping. Since the file is a VIS file, the intermediate processes will split the image into even and odd framelets which are recombined once mapped. Since this file is an EDR, thmvistrim and thmvisflat will be run by default to clean up the image.
