List files of a GLASS archive composite folder — glass_list

Reads the GLASS archive directory listing for one composite folder and returns the matching data files as a manifest (filename, URL, doy, tile). The listing is plain HTML with relative links, so no credentials or API keys are needed.

Usage

glass_list_files(
  variant_id,
  year = NULL,
  doy = NULL,
  tiles = NULL,
  ext = "hdf"
)

Arguments

variant_id: Registry variant key, e.g. "LAI_MODIS_250M".
year: Calendar year of the composite (folder level). May be NULL for "flat" layout variants (e.g. KGClim, AGB). Required for the other layouts.
doy: Day of year of the composite, integer or "217"; NULL only allowed for "flat" variants (whole collection) and "year_files" variants (all composites of the year; otherwise files are filtered by the A{year}{doy} fragment in their names).
tiles: Optional tile selector: a character vector like c("h28v05") or a data frame with h/v columns (e.g. the output of glass_tiles_for_bbox()).
ext: File extensions to keep, e.g. c("hdf", "hdf.xml"); default "hdf" (the data files).

Value

A tibble with columns filename, url, variant_id, year, doy, tile, ext.

Examples

if (FALSE) { # \dontrun{
glass_list_files("LAI_MODIS_250M", year = 2018, doy = 217, tiles = "h28v05")
} # }
