Input Scenes
The name of the folder that contains the panchromatic (PAN) and multispectral (MS) image pairs to process. The files must be in PCIDSK (.pix) format. The folder can be the output folder of the Data Ingest module or the Tie-Point Collection and Refinement module.
Output Folder
The name of the folder to which to write the exported TIFF files and associated text file of RPC information.
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.
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.
RPC File Format
Format of the RPC text file.
Elevation Reference/Datum
The vertical reference for the elevation values in the RPC.
Available values are as follows:
Export to GeoTIFF
Select this check box to export the PCIDSK files to GeoTIFF.

Preprocessing requirements
Before running this module, the following requirements must be met to ensure the job processes successfully and produces accurate results:
Input scenes: the folder must contain panchromatic (PAN) and multispectral (MS) image pairs to process. The files must be in PCIDSK (.pix) format. The folder can be the output folder of the Data Ingest module or the Tie-Point Collection and Refinement module.
The Export to GeoTIFF and RPC module reads the Input Scenes folder for ingested PAN and MS image pairs with collected GCPs.
Job results
The Export to GeoTIFF and RPC module exports the input imagery to TIFF, and then creates a report on the number of GCPs collected between the PAN and MS images, and RMS errors. You can inspect this report to assess the accuracy of the coregistration of the PAN and MS imagery.
The module also creates a control point (CP) information file in ASCII format (.inf). The CP information file contains coordinate information and relevant description. The Memo field contains the OrthoEngine GCP ID and base name of the source file.
