fastbioclim (version 0.3.0)

bioclim_fast: Tiled, Out-of-Core Bioclimatic Variable Calculation

Description

Internal function to calculate bioclimatic variables for very large datasets by processing them in tiles. It reads data from file paths using `exactextractr` and performs calculations with `Rfast`.

Usage

bioclim_fast(
  bios,
  n_units,
  tmin_path = NULL,
  tmax_path = NULL,
  prcp_path = NULL,
  tavg_path = NULL,
  srad_path = NULL,
  mois_path = NULL,
  period_length = 3,
  circular = TRUE,
  user_region = NULL,
  tile_degrees = 5,
  output_dir = tempdir(),
  verbose = TRUE,
  ...
)

Value

Character string: Path to the temporary directory containing intermediate `.qs2` files, to be used by an assembly function.

Arguments

bios

Numeric vector of variables to compute.

n_units

Integer, number of layers per variable.

period_length

Integer, length of a calculation period.

circular

Logical, whether to wrap periods.

user_region

An `sf` or `SpatVector` object for the area of interest.

tile_degrees

Numeric, size of processing tiles.

output_dir

Character, path for temporary files.

verbose

Logical, If `TRUE`, prints messages.

...

File paths for climate variables (e.g., `tmin_path`) and static indices (e.g., `warmest_period_path`).
