5.6.5        Mosaic Modules: Mosaic Geometry

Command Line Equivalent: run_mosaic_geom

Default Output Directory: <output_dir>

Depends On: Initial Settings; Mosaic Settings; Fiducial Image Frame

 

PURPOSE

This module allows users to mosaic only the BCDs that overlap a user-specified spatial area. It takes in the full lists of input images, uncertainty files and mask files, and creates new lists that include only those images that overlap a user-supplied Fiducial Image Frame (FIF) table. The new lists are then used by subsequent modules in the Mosaic pipeline. 

 

INPUT

This module does not have any input parameters. However, it requires the FIF table specified in the input namelist to have been edited by hand to specify the area that the user wishes to mosaic.

 

COMMAND LINE INPUT

See INPUT.

 

OUTPUT

The module creates working lists of images, and associated masks and uncertainty files, that are then automatically used by later modules to create the mosaic image. The filenames created are as follows:

 

  • geom_ImageList.txt
  • geom_DmaskList.txt
  • geom_SigmaList.txt
  • geom_rmask_ImageList.txt
  • geom_fif.tbl
  • geom_Tile.tbl
  • geom_Int_Img.tbl

 

 

DISCUSSION

For complete instructions on how to use this module to create a mosaic of a subset of a larger dataset, please see §5.3: Mosaicking a Portion of the Total FIF. This includes information on how to modify the FIF.tbl file to specify the new area.
