Process CoralTemp NetCDF files into a combined raster

process_CoralTemp.Rd

This function reads, crops, masks, and (optionally) downsamples CoralTemp NetCDF (.nc) files, then combines them into a single raster stack. Processing can be done sequentially with lapply or in parallel with future.apply::future_lapply.

Usage

process_CoralTemp(
  input,
  polygon,
  crop = TRUE,
  mask = TRUE,
  downsample = FALSE,
  res = 0.1,
  variable = "sst",
  crs = "EPSG:7844",
  combinedfilename = NULL,
  mc.cores = 1,
  silent = TRUE
)

Arguments

input

Character. Path to directory containing .nc files.

polygon

sf polygon object used for cropping/masking.

crop

Logical. If TRUE, crop rasters to polygon extent. Default TRUE.

mask

Logical. If TRUE, mask rasters by polygon. Default TRUE.

downsample

Logical. If TRUE, resample rasters to coarser resolution. Default FALSE.

res

Numeric. Resolution for downsampling. Default 0.1.

variable

Character. Variable name (currently unused placeholder). Default "sst".

crs

Character. Target CRS for final raster (e.g., "EPSG:7844").

combinedfilename

Character. Output file path (.tif or .rds).

mc.cores

Integer or NULL. Number of cores for parallel processing. If NULL, sequential base::lapply is used. Default 1.

silent

Logical. If FALSE, print messages when files are processed.

Value

Writes a combined raster file to combinedfilename. Invisibly returns TRUE.

Examples

if (FALSE) { # \dontrun{
process_CoralTemp(
  input = "data/CoralTemp/",
  polygon = sf::st_read("gbr_polygon.shp"),
  combinedfilename = "outputs/CoralTemp_combined.tif",
  mc.cores = 4,
  silent = FALSE
)
} # }
