t.sentinel3.import - GRASS GIS manual

NAME

t.sentinel3.import - Import and pre-process Sentinel-3 data from the Copernicus program into a Space Time Raster Dataset (STRDS)

KEYWORDS

imagery, satellite, Sentinel, temporal, import, optical, thermal

SYNOPSIS

t.sentinel3.import

t.sentinel3.import --help

t.sentinel3.import [-ecdjkonr] input=string[,string,...] output=name [title=string] [description=string] product_type=string bands=string[,string,...] [anxillary_bands=string[,string,...]] [flag_bands=string[,string,...]] [maximum_solar_angle=float] [basename=string] [nprocs=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

-e: Extend existing STRDS (requires overwrite flag)
-c: Import LST in degree celsius (default is kelvin)
-d: Import data with decimals as double precision
-j: Write metadata json for each band to LOCATION/MAPSET/cell_misc/BAND/description.json
-k: Keep original cell values during interpolation (see: r.fill.stats)
-o: Process oblique view (default is nadir)
-n: Import data at native resolution of the bands (default is use current region)
-r: Rescale radiance bands to reflectance
--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

input=string[,string,...] [required]: Sentinel-3 input data; Either a (comma separated list of) path(s) to Sentinel-3 zip files or a textfile with such paths (one per row)
output=name [required]: Name of the output space time raster dataset (STRDS)
title=string: Title of the resulting STRDS
description=string: Description of the resulting STRDS
product_type=string [required]: Sentinel-3 product type to import (currently, only S3SL1RBT and S3SL2LST are supported); Options: S3SL1RBT, S3SL2LST; Default: S3SL2LST
bands=string[,string,...] [required]: Data bands to import (e.g. LST, default is all available); Default: all
anxillary_bands=string[,string,...]: Anxillary data bands to import (e.g. LST_uncertainty, default is None, use "all" to import all available)
flag_bands=string[,string,...]: Quality flag bands to import (e.g. bayes_in, default is None, use "all" to import all available)
maximum_solar_angle=float: Import only pixels where solar angle is lower or equal to the given maximum
basename=string: Basename used as prefix for map names (default is derived from the input file(s))
nprocs=integer: Number of threads for parallel computing; Default: 1

DESCRIPTION
EXAMPLES
- Import all Sentinel-3 data in a given directory

DESCRIPTION

t.sentinel3.import is a wrapper around the i.sentinel3.import module and supports all relevant flags and options of that module. t.sentinel3.import takes a directory or a list of files as input, groups those files by day and track and, processes each group with i.sentinel3.import and registers all resulting maps in the output SpaceTimeRasterDataset (STRDS). If multiple cores are given in the nprocs option, groups are processed in parallel. If more cores than groups are available, multiple cores may be made available to each i.sentinel3.import process.

For more information on pre-prcessing Sentinel-3 data, please consult the manual of i.sentinel3.import.

EXAMPLES

Import all Sentinel-3 data in a given directory

t.sentinel3.import input=/data/Sentinel3/SLSTR/ output=Sentinel_3_SLSTR_RBT_L2 \
  nprocs=8 product_type=S3SL1RBT -erj \
