Parameter descriptions

Input Folder

The path and name of the folder containing valid GDB-supported images; typically, this is the output folder of the Data Ingest module.

Output Folder

The path and name of the folder to which to write the output files.

Overwrite Results

Select this check box to overwrite the existing output files, if any exist. If this check box is left clear, and an output file exists in the relevant folder, the status of the job displays a message informing you of the existence and name of the output file. The message is also written to the event log of the job.

Include Subfolders

Select this check box to include subfolders in the search.

Send Email

If necessary, you can set up CATALYST Enterprise to send an email notification on job start and job completion.

With this check box selected, an email message is sent to each address specified in the Email Addresses box after the job starts and on completion.

You can specify one or more addresses, and each must be separated by a comma or a semi-colon. The email address of the user currently logged in displays by default.

DEM Source

The name of a file or folder containing DEM tiles.

This value may be the name of a single DEM file, the name of a folder containing DEM tiles, or the name of an index.txt file.

If the name of an existing folder is specified, the module reads the folder for a file named index.txt, and a set of DEM raster tiles. The index.txt file lists the DEM files contained in the specified folder and provides information describing each raster tile.

For more information on the format of the index.txt file and specific requirements for the individual DEM tiles, see Format of the DEM index file.

Pre-classified file directory

Optionally specify a folder that contains spectrally classified files. If left empty, the job will generate a classification file by running SPECLASS. The classification files should follow CATALYST Enterprise naming convention. That is, if the input MS image file name is in the form of ${baseid}_${level}_${prodtype}${ext}, the original ${prodtype} should be replaced by "CLS" to indicate it is a classification file. Otherwise the name should be appended with "_CLS". For example:

Calculate per-pixel angle

Once checked, the job generates an angle file from the input data, and user can no longer supply their own angle file.

Angle file directory

Optionally specify a folder that contains angle files. If left empty, the job generates an angle file by running SOLVIEWZAZ. The angle files should follow CATALYST Enterprise naming convention. That is, if the input image file name is in the form of ${baseid}_${level}_${prodtype}${ext}, the original ${prodtype} should be replaced by "ANGL" to indicate it is a angle file. Otherwise the name should be appended with "_ANGL". For example:
