| Processor Description - S2 MCI |
|
The S2 MCI processor can be invoked from the menu by selecting
Processing->Thematic Water Processing->S2 MCI Processor....
On the command line the MCI processor is available by means of the Graph Processing Tool gpt
which is located bin folder within the installation directory.
Typing gpt Mci.s2 -h displays further information.
Selecting the S2 MCI Processor command from the menu pops up the following dialog:
Source product: Here the user specifies the source product. The combo box presents a list of all products opened in the application. The user may select one of these or, by clicking on the button next to the combo box, choose a product from the file system.
Name: Used to specify the name of the target product.
Save as: Used to specify whether the target product should be saved to the file system. The combo box presents a list of available file formats. The text field or the button next to it allow to specify a target directory.
Open in SNAP: Used to specify whether the target product should be opened in the application. When the target product is not saved, it is opened automatically.
Preset: Select one of the available presets from the predefined list. Available presets are:
A preset selects the bands used to calculate the baseline, the signal band, the line height band and the slope band.
Lower baseline band name: The name for the lower wavelength band defining the baseline. Enter a band name or select one of the list of available bands (only available when an input product is already selected).
Upper baseline band name: The name of the upper wavelength band defining the baseline. Enter a band name or select one of the list of available bands (only available when an input product is already selected).
Signal band name: The name of the signal band, i.e. the band for which the baseline height is calculated. Enter a band name or select one of the list of available bands (only available when an input product is already selected).
Line height band name: The name of the line height band in the target product.
Generate slope parameter: Activates or deactivates calculating the slope parameter.
Slope band name: The name of the slope band in the target product (disabled when calculating the slope is deactivated)
Mask expression: A ROI-mask expression to be evaluated during processing. Used to define pixels of interest.
Cloud correction factor: The cloud correction factor used during calculation. See algorithm documentation for details.
Invalid MCI value: The value written to a target pixel when it is excluded from the ROI or the MCI calculation yields an invalid result.
Run Creates the target product. The MCI processing is actually deferred until its band data are accessed, either by writing the product to a file or by viewing its band data. When the Save as option is checked, the MCI processing is triggered automatically.
Close Closes the dialog.
File The entries found in this menu allow to save the current processing parameters to disk and to open a saved parameter set from disk.
Help Contains entries for accessing the help pages and information about this processor.
