sen2cor: Correct L1C products using sen2cor
In pobsteta/theia2r: An R toolbox to find, download and preprocess Sentinel-2 data

Description Usage Arguments Value Note Author(s) Examples

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)

`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()`).

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