s2_rgb: Create RGB images from S2 reflectance products.

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

Description

Function to create RGB images from Sentinel-2 reflectances. natural: B4, B3, B2 near infrarouge: B8, B4, B3 far infrarouge: B12, B8, B4 vegetation: B11, B8, B2

Usage

s2_rgb(infiles, rgblist, tilesdir, extent, mosaicdir, project,
  outdir = ".", subdirs = NA, tmpdir = NA, rmtmp = TRUE,
  format = NA, compress = "DEFLATE", vrt_rel_paths = NA,
  parallel = FALSE, resolution = 10, overwrite = FALSE)

Arguments

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 theia2r naming convention (safe_shortname).
rgblist	rgblist
tilesdir	Directory of tiles
mosaicdir	Directory of mosaic
outdir	(optional) Full name of the existing output directory where the files should be created. Default is the same directory of input reflectance files. # FIXME use a subdir with product name
subdirs	(optional) Logical: if TRUE, different indices are placed in separated outfile subdirectories; if FALSE, they are placed in outfile directory; if NA (default), subdirectories are created only if more than a single spectral index is required.
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)
format	(optional) Format of the output file (in a format recognised by GDAL). Default is the same format of input images (or 'GTiff' in case of VRT input images).
compress	(optional) In the case a GTiff format is present, the compression indicated with this parameter is used.
vrt_rel_paths	Directory 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.
resolution	Resolution
overwrite	(optional) Logical value: should existing thumbnails be
overwritten?	(default: TRUE)

Value

A vector with the names of the created images.
