Download zip files from FIA datamart — fia

The zip files are smaller than just the *_TREE.csv, so this just downloads the whole zip and extracts the required CSV files. Uses curl::multi_download() which resumes partial skips already completed downloads when run subsequent times.

Usage

fia_download(
  states,
  download_dir = "fia",
  extract = c("forestTIME", "rFIA", "all", "none"),
  keep_zip = TRUE
)

Arguments

states: Vector of state abbreviations; for all states use state.abb.
download_dir: Where to save the zip files.
extract: Which files to extract from the downloaded zip file—those needed by forestTIME, those needed by rFIA (in addition to all the tables forestTIME needs), all the files, or none.
keep_zip: Logical; keep the .zip file after CSVs are extracted? Defaults to TRUE.

Value

Returns nothing.

Examples

if (FALSE) { # \dontrun{
# "Standard" download
fia_download(states = c("RI", "DE"))

# Extract enough tables so it works with rFIA::readFIA() also
fia_download(states = c("RI", "DE"), extract = "rFIA")
} # }
