The function merge 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.
s2_merge(infiles, outdir = ".", subdirs = NA, tmpdir = NA, rmtmp = TRUE, format = NA, compress = "DEFLATE", vrt_rel_paths = NA, out_crs = "", parallel = FALSE, overwrite = FALSE, .log_message = NA, .log_output = NA)
infiles | A vector of input filenames. Input files are paths of products already converted from SAFE format to a format managed by GDAL (use s2_translate to do it); their names must be in the sen2r naming convention (safe_shortname). |
---|---|
outdir | (optional) Full name of the output directory where
the files should be created (default: current directory).
|
subdirs | (optional) Logical: if TRUE, differet output products are
placed in separated |
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 |
out_crs | (optional) proj4string (character) of the output CRS
(default: the CRS of the first input file). The tiles with CRS different
from |
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. |
overwrite | Logical value: should existing output files be overwritten? (default: FALSE) |
.log_message | (optional) Internal parameter
(it is used when the function is called by |
.log_output | (optional) Internal parameter
(it is used when the function is called by |
A vector with the names of the merged products (just created or already existing).
