The function uses sen2cor to manually correct L1C products. Standalone version of sen2cor 2.5.5 is used.

sen2cor(l1c_prodlist = NULL, l1c_dir = NULL, outdir = NULL,
  proc_dir = NA, tmpdir = NA, rmtmp = TRUE, tiles = NULL,
  parallel = FALSE, overwrite = FALSE, .log_message = NA,
  .log_output = NA)

Arguments

l1c_prodlist

List of L1C product names to be corrected. They can be both product names with full/relative path or only names of SAFE products (in this case, also l1c_dir argument must be provided). SAFE products must be unzipped. Note that, at this stage, all products must be in the same directory (this will be fixed).

l1c_dir

Full or relative path of input L1C products. If NULL (default), l1c_prodlist must already be a vector of full paths.

outdir

Directory where output L2A products will be placed. If NULL (default), each product is left in the parent directory of l1c_prodlist.

proc_dir

(optional) Directory where processing is applied. If NA (default), processing is done in l1c_dir and output L2A product is then moved to outdir, unless l1c_dir is a subdirectory of a SAMBA mountpoint under Linux: in this case, L1C input products are copied in a temporary directory (specified with argument tmpdir), processing is done there and then L2A is moved to outdir. This is required under Linux systems when l1c_dir is a subdirectory of a unit mounted with SAMBA, otherwise sen2cor would produce empty L2A products.

tmpdir

(optional) Path where processing is performed if a temporary working directory is required (see argument proc_dir). Be sure tmpdir not to be a SAMBA mountpoint under Linux. Default is a temporary directory.

rmtmp

(optional) Logical: should temporary files be removed? (Default: TRUE)

tiles

Vector of Sentinel-2 Tile strings (5-length character) to be processed (default: process all the tiles found in the input L1C products).

parallel

(optional) Logical: if TRUE, sen2cor instances are launched in parallel using multiple cores; if FALSE (default), they are launched in series on a single core. The number of cores is automatically determined; specifying it is also possible (e.g. parallel = 4).

overwrite

Logical value: should existing output L2A products be overwritten? (default: FALSE)

.log_message

(optional) Internal parameter (it is used when the function is called by sen2r()).

.log_output

(optional) Internal parameter (it is used when the function is called by sen2r()).

Value

Vector character with the list ot the output products (being corrected or already existing)
