Process Corine Land Cover (CLC) data for the IASDT

Processes Corine Land Cover (CLC) data for the Invasive Alien Species Digital Twin (IASDT). Calculates percentage coverage and most common classes per grid cell at three CLC levels, plus eunis19 and SynHab habitat types. Prepares a reference grid and optionally generates percentage coverage maps as JPEG.

Usage

clc_process(
  env_file = ".env",
  min_land_percent = 15L,
  plot_clc = TRUE,
  n_cores_plot = 5L,
  strategy = "multisession"
)

Arguments

env_file

Character. Path to the environment file containing paths to data sources. Defaults to .env.

min_land_percent

Numeric. Minimum land percentage per grid cell for the reference grid. Default: 15.

plot_clc

Logical. If TRUE, plots percentage coverage for CLC levels and habitat types. Default: TRUE.

n_cores_plot

Integer. Number of CPU cores to use for parallel plotting. Default: 5L.

strategy

Character. The parallel processing strategy to use. Valid options are "sequential", "multisession" (default), "multicore", and "cluster". See future::plan() and ecokit::set_parallel() for details.

Value

Returns invisible(NULL); saves processed data and optional plots to disk.
