MFILE
Specifies the name of a folder, image file, or text file that contains the input raw images to be processed. Wildcards (*) can be used.
If a directory name is specified or if multiple file names are entered, all images in MFILE should be processed using the parameters set for SATMODEL.
If a directory is specified, then the DBGC, MMSEG, and ORBIT parameters are set to a single value for all input images. If a text file is specified, the files listed in the text file are processed with the listed parameters. In this case, the DBGC, MMSEG, and ORBIT parameters are read from the text file for each image, and those parameters can be left blank.
If one file is specified for MFILE, then the model computed will be an independent model (one image).
DBGC
Specifies the ground control point (GCP) segment or layer in the input raw image to use to compute the model.
If a directory is specified for MFILE, this segment number will be applied to all images. If a text file is specified, DBGC is read from the text file, and this parameter can be left blank. If no value is specified, the default four-corner coordinates in the orbit segment will be used as GCPs to compute an approximate model for non-RADARSAT-2 images. For RADARSAT-2 images, the orbit and RFModel segments associated with the data will be used to compute Toutin's hybrid model.
ORBIT
Specifies the orbit segment or layer in the input image to use to compute the model.
If a directory is specified for MFILE, this segment number will be applied to all images. If a text file is specified, ORBIT is read from the text file, and this parameter can be left blank. If no value is specified, the last orbit segment will be used automatically.
MMSEG
Specifies the math model segment or layer to store the model.
If a directory is specified for MFILE, this segment number will be applied to all images. If a text file is specified, MMSEG is read from the text file, and this parameter can be left blank. If no value is specified, a new segment is created.
MAPUNITS
Specifies the projection string for the output model.
The standard definitions are as follows:
For a complete list of supported projections and Earth models, see Understanding map projections. The format of the map units string is described in Output units.
If this parameter is not specified, the map units of the specified GCP segment are used. If no GCP segment is specified, the UTM unit stored in the orbit segment is used.
REPORT
Specifies where to direct the generated report.
Available options are:

SATMODEL computes the math model of one or more satellite images using Toutin's model. This includes bundle adjustment of multiple scenes, using ground control points (GCPs) or tie points, or both.
The output is a refined math model for each image, saved either to a math model segment in the image file or to the OrthoEngine project file, depending on the input.
[FILE][DBGC][ORBIT][MMSEG]
If the DBGC (InputGCP) parameter is not specified, SATMODEL uses the four corner points and scene center point stored in the ORBIT (InputORB) segment as GCPs; however, these points are not available for every format.
If DBGC (InputGCP) is not specified and these points are not available, SATMODEL exits with an error. The corners points are only an estimate and are not accurate. Use them only when accurate GCPs cannot be obtained.
