Input Folder
The path and name of the folder that contains the Sentinel-2 imagery to pansharpen.
Output Folder
The path and name of the folder to which to write the output files.
Output File Type
The format of the output file.
For more information on the supported file formats, see GDB-supported file formats.
Output File Options
The options to apply when creating the output file or files. The available options are specific to the file format; in each case, the default of no options is allowed.
For more information on the options available for the output file type you specify, see GDB-supported file formats.
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.
Pansharpening Method
The method to use for pansharpening.Resampling Method
Available only when UNB Pansharp is selected for Pansharpening Method, the resampling method to use during processing.
Enhance
Specifies whether to generate a refined pansharpened image.
The enhance option is only available for UNB pansharpening.
Edge Sharpen
Amount of sharpening to image edges to apply. A value of 1.0 (default) means no edge sharpening. Values greater than 1.0 apply greater sharpening. Values greater than 2.0 are not recommended.
Applying edge sharpening makes image more visually appealing but may degrade radiometric similarity with the original multispectral (MS) data.
AdaptRadiometry
Method to adapt the output spectral values to those of the input multispectral (MS) image.
Adapting the radiometry can better match to the original multispectral image. The two methods are linear regression based on a small sliding window and an estimate of the Modulation Transfer Function (MTF).
Source Background Type
The method to use to determine which pixels in the source image to process as background (NoData) pixels. In general, if a pixel is considered NoData, the module processes it in a specific manner.
If the Any option or the All option is selected, a value must be specified for the Source Background Value parameter.
File Metadata, else None: reads the NoData value from the input-file metadata. The module first checks for the file-level metadata tag NO_DATA_VALUE in the source raster. If the tag is present, this value is used as a default for all channels in the file. Next, the module checks for channel-level NoData tags; if one is found, the channel-level value overrides the file-level value for that channel.
If there are channel-level NoData tags, but no file-level tag, a pixel is considered as NoData if each of the channels with a NoData tag corresponds to its NoData value. In this case, channels without a NoData tag are ignored when identifying background pixels.
If the file does not contain NoData tags, all pixels in the source image are considered valid.
For specific examples, see the Source Background Value parameter description.
Source Background Value
The source background value is provided as either a single number (applied to all channels) or as a pixel "stack" (a comma-delimited list of values). If a pixel stack is provided, but the number of values does not equal the number of channels, the list is truncated or the last value is repeated as necessary. The background values provided is truncated to the range allowed by the source image data type.
Source Background Type set to All and Source Background Value set to 0: a pixel is considered background if all three channels are zero.

Preprocessing requirements
Before running this module, the following requirements must be met to ensure the job processes successfully and produces accurate results:
Module details
The Pansharpening Sentinel-2 Imagery module automatically sharpens additional bands contained in the 20-meter and 60-meter swaths based on the 10-meter swath. All pansharpened bands are then merged into one file.
The output pansharpened image products will be a single file for each 10-meter, 20-meter, and 60-meter image pair.
The Pansharpening Sentinel-2 Imagery module supports processing using GPUs and multi-core processors.
Job results
For each image pair found in the input folder, the Pansharpening module creates a single pansharpened PCIDSK file.
Output image file names are structured as follows:
<SCENE_ID>_<STATE>_PSH.pix
Output images are located in the folder specified for the Output Folder parameter.
This module transfers file-based metadata tags from the source files to the output. The transferred metadata information includes the date and time that the input scene was acquired, the sensor or platform name, and the ID of the scene.
