Download climate classification data

Source: R/download.R
download_koppen_geiger.Rd

The download_koppen_geiger() function accesses and downloads climate classification data from the Present and future Köppen-Geiger climate classification maps at 1-km resolution(link for article; link for data).

Usage

download_koppen_geiger(
  data_resolution = c("0.0083", "0.083", "0.5"),
  time_period = c("Present", "Future"),
  directory_to_save = NULL,
  acknowledgement = FALSE,
  download = FALSE,
  remove_command = FALSE,
  unzip = TRUE,
  remove_zip = FALSE,
  hash = FALSE
)

Arguments

data_resolution

character(1). Available resolutions are "0.0083" degrees (approx. 1 km), "0.083" degrees (approx. 10 km), and "0.5" degrees (approx. 50 km).

time_period

character(1). Available times are "Present" (1980-2016) and "Future" (2071-2100). ("Future" classifications are based on scenario RCP8.5).

directory_to_save

character(1). Directory to save data. Two sub-directories will be created for the downloaded zip files ("/zip_files") and the unzipped shapefiles ("/data_files").

acknowledgement

logical(1). By setting TRUE the user acknowledges that the data downloaded using this function may be very large and use lots of machine storage and memory.

download

logical(1). FALSE will generate a *.txt file containing all download commands. By setting TRUE the function will download all of the requested data files.

remove_command

logical(1). Remove (TRUE) or keep (FALSE) the text file containing download commands.

unzip

logical(1). Unzip zip files. Default is TRUE.

remove_zip

logical(1). Remove zip files from directory_to_download. Default is FALSE.

hash

logical(1). By setting TRUE the function will return an rlang::hash_file() hash character corresponding to the downloaded files. Default is FALSE.

Value

  • For hash = FALSE, NULL

  • For hash = TRUE, an rlang::hash_file character.

  • Zip and/or data files will be downloaded and stored in respective sub-directories within directory_to_save.
