One-day simulation for spatially-distributed forest stands

Functions that allow calling local models spwb_day or growth_day, for a set of forest stands distributed in specific locations and a given date. No spatial processes are simulated.

Usage

spwb_spatial_day(
  sf,
  meteo = NULL,
  date,
  SpParams,
  local_control = defaultControl(),
  parallelize = FALSE,
  num_cores = detectCores() - 1,
  chunk_size = NULL,
  progress = TRUE
)

growth_spatial_day(
  sf,
  meteo = NULL,
  date,
  SpParams,
  local_control = defaultControl(),
  parallelize = FALSE,
  num_cores = detectCores() - 1,
  chunk_size = NULL,
  progress = TRUE
)

Arguments

sf: An object of class sf with landscape information (see spwb_spatial).
meteo: Meteorology data (see spwb_spatial).
date: A string with the date to be simulated.
SpParams: A data frame with species parameters (see SpParamsMED).
local_control: A list of local model control parameters (see defaultControl).
parallelize: Boolean flag to try parallelization (will use all clusters minus one).
num_cores: Integer with the number of cores to be used for parallel computation.
chunk_size: Integer indicating the size of chunks to be sent to different processes (by default, the number of spatial elements divided by the number of cores).
progress: Boolean flag to display progress information for simulations.

Value

An object of class sf the same name as the function called containing three elements:

geometry: Spatial geometry.
id: Stand id, taken from the input.
state: A list of model input objects for each simulated stand, to be used in subsequent simulations.
result: A list of model output for each simulated stand.

Details

Simulation functions accept different formats for meteorological input (described in spwb_spatial).
