s2_warped: Make a warped of each band of S2 tiles with the same date and...

In pobsteta/shiny-cnes: Package to download space image from CNES server (theia, peps...)

Description

The function mosaic the input Sentinel-2 files with the same date, orbit number, product type and file format. Outputs are a set of products in the same format of corresponding input files.

Usage

s2_warped(infiles, tilesdir, translatedir, outdir = ".", subdirs = NA,
  tmpdir = NA, rmtmp = TRUE, format = NA, compress = "DEFLATE",
  vrt_rel_paths = NA, resolution = 10, parallel = FALSE,
  overwrite = FALSE)

Arguments

infiles	A vector of input filenames. Input files are paths of products already converted to a format managed by GDAL.
outdir	(optional) Full name of the output directory where the files should be created (default: current directory). outdir can bot be an existing or non-existing directory (in the second case, its parent directory must exists). If it is a relative path, it is expanded from the common parent directory of infiles.
tmpdir	(optional) Path where intermediate files (VRT) will be created. Default is a temporary directory.
rmtmp	(optional) Logical: should temporary files be removed? (Default: TRUE). This parameter takes effect only if the output files are not VRT (in this case temporary files cannot be deleted, because rasters of source bands are included within them).
format	(optional) Format of the output file (in a format recognised by GDAL). Default is to maintain each input format.
compress	(optional) In the case a GTiff format is present, the compression indicated with this parameter is used.
vrt_rel_paths	(optional) Logical: if TRUE (default on Linux), the paths present in the VRT output file are relative to the VRT position; if FALSE (default on Windows), they are absolute. This takes effect only with format = "VRT".
parallel	(optional) Logical: if TRUE, the function is run using parallel processing, to speed-up the computation for large rasters. The number of cores is automatically determined; specifying it is also possible (e.g. parallel = 4). If FALSE (default), single core processing is used.
overwrite	Logical value: should existing output files be overwritten? (default: FALSE)
out_crs	(optional) proj4string (character) of the output CRS (default: the CRS of the first input file). The tiles with CRS different from out_crs will be reprojected (and a warning returned).
.log_message	(optional) Internal parameter (it is used when the function is called by theia2r()).
.log_output	(optional) Internal parameter (it is used when the function is called by theia2r()).

Value

A vector with the names of the merged products (just created or already existing).
