## S4 method for signature 'list'
preprocessMODIS(x, vi = c("NDVI", "EVI"), dsn = getwd(),

A named list of local MODIS SDS layers per product as returned by runGdal.

vi

character. Vegetation index under consideration. Currently available options are "NDVI" (default) and "EVI".

dsn

character. Target folder for file output.

ext

Extent, or any object from which an Extent can be extracted, see crop. If missing, layer clipping is skipped.

interval

See temporalComposite.

whit

logical. TRUE (default) invokes gap-filling via modified Whittaker smoothing, see whittaker.raster.

cores

integer. Number of cores for parallel processing.

...
