Estimate B620 for S2 (CLI)
Overview
The processor can be used with the command line tool
gpt
. General information about GPF and GPT can be
found on their help
pages. Specific help for the S2B620 processor can be obtained
with: ${SNAP-INSTALL-DIR}/bin/gpt -h S2B620
This will show the following help:
Usage:
gpt S2B620 [options]
Description:
Derive band at 620 using the band at 665.
Source Options:
-SsourceProduct=<file> An atmospherically corrected Sentinel-2 product
This is a mandatory source.
Parameter Options:
-PincludeSourceBands=<boolean> Whether to include source data or only generate band at 620nm
Default value is 'True'.
-PlimitInputRange=<boolean> Limit input range [0, 0.065]
Default value is 'True'.
-Pshapefile=<path> An ESRI shapefile, providing the considered geographical region(s).
-PvalidExpression=<string> The valid expression defining the considered geographical region.
-PwktRegion=<geometry> The considered geographical region as a geometry in well-known text format (WKT).

Parameters
sourceProduct |
This defines the source product on which the processing is
performed. The product must contain a band at 665 nm. |
limitInputRange |
Whether the input range should be limited to the reliable value
range. The range is defined * as [0, 0.065]. |
validExpression |
This expression defines which pixels are valid for processing.
It must follow the rules of Band Maths. |
shapefile |
A shapefile can be selected to define the valid region for the
processing. |
wktRegion |
A geometry using WGS84 coordinates can be specified following
the WKT Format. |
includeSourceBands |
Whether to include source data or only generate the band at 620
nm. |
