Processor Description - FLH/MCI

User Interface

The FLH/MCI processor can be invoked in the Sentinel Toolbox from tool menu by selecting Processing->Thematic Water Processing->FLH/MCI Processor.... On the command line the FLH/MCI processor is available by means of the Graph Processing Tool gpt which is located in the Sentinel Toolbox bin directory. Typing gpt FlhMci -h displays further information.

Selecting the FLH/MCI Processor command from the Sentinel Toolbox tool menu pops up the following dialog:

Source Product Group

Source product: Here the user specifies the source product. The combo box presents a list of all products opened in the Sentinel Toolbox. 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.

Target Product Group

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 Sentinel Toolbox. When the target product is not saved, it is opened in the Sentinel Toolbox automatically.

Processing Parameters Panel

Preset: Select one of the available presets from the predefined list. The specific parameters override the values of the preset. Available presets are:

Preset Lower Baseline Band Name Upper Baseline Band Name Signal Band Name Line Height Band Name Slope Band Name Mask Expression
MERIS L1b MCI radiance_08 radiance_10 radiance_9 MCI MCI_slope NOT l1_flags.LAND_OCEAN AND NOT l1_flags.BRIGHT AND NOT l1_flags.INVALID
MERIS L2 FLH reflec_9 reflec_7 reflec_8 FLH FLH_slope l2_flags.WATER
MERIS L2 MCI reflec_10 reflec_8 reflec_9 MCI MCI_slope l2_flags.WATER
OLCI L1b MCI Oa12_radiance Oa10_radiance Oa11_radiance MCI MCI_slope (!quality_flags.land || quality_flags.fresh_inland_water) && ! quality_flags.invalid
OLCI L2 FLH Oa11_reflectance Oa08_reflectance Oa10_reflectance FLH FLH_slope WQSF_lsb.WATER || WQSF_lsb.INLAND_WATER
OLCI L2 MCI Oa12_reflectance Oa10_reflectance Oa11_reflectance MCI MCI_slope WQSF_lsb.WATER || WQSF_lsb.INLAND_WATER

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 FLH/MCI value: The value written to a target pixel when it is excluded from the ROI or the FLH/MCI calculation yields an invalid result.

Button Group

Run Creates the target product. The FLH/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 FLH/MCI processing is triggered automatically.

Close Closes the dialog.

Menu Group

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.
