Split a multi-band wapor_map() stack into one file per date

wapor_map(separate_files = FALSE) (the default) writes one multi-band GeoTIFF named <product>.<first date>_<last date>.tif, with one band per time step named by its start date. Local analysis (data_source = "local") needs one file per time step. This writes <product>.<date>.tif next to the stack (or into folder), the same layout as wapor_map(separate_files = TRUE), and skips files that already exist.

Usage

wapor_unstack_map(
  path,
  folder = dirname(path),
  overwrite = FALSE,
  remove_stack = FALSE
)

Arguments

path: Character. Path to the multi-band GeoTIFF.
folder: Character. Output folder. Defaults to the stack's folder.
overwrite: Logical. Overwrite existing per-date files. Default FALSE.
remove_stack: Logical. Delete the stack after a successful split, so local readers do not see both. Default FALSE.

Value

Character vector of per-date file paths, invisibly.

Examples

if (FALSE) { # \dontrun{
stack <- wapor_map(c(35, 33, 36, 34), "L1-AETI-D",
                   c("2023-01-01", "2023-03-31"), folder = "wapor_data")
wapor_unstack_map(stack)
} # }
