Convert raster data to PRIO-GRID

Usage

pg_from_raster(
  x,
  variable,
  aggregation,
  time = NULL,
  layer = NULL,
  na_values = NULL,
  disagg_method = c("near", "bilinear", "cubic"),
  return = c("data", "raster", "result"),
  config = priogrid::pg_current_config(),
  filename = NULL,
  overwrite = FALSE,
  ...
)

Arguments

x: A SpatRaster or one or more raster-file paths.
variable: Name of the resulting variable.
aggregation: Spatial aggregation passed as agg_fun to priogrid::robust_transformation().
time: Optional date or year for each raster layer.
layer: Optional layer selection passed to [[.
na_values: Optional source values to replace with NA.
disagg_method: Disaggregation method.
return: One of "data", "raster", or "result".
config: A PRIO-GRID configuration object.
filename: Optional output filename.
overwrite: Replace an existing output file?
...: Additional arguments passed to priogrid::robust_transformation().

Value

A data frame, SpatRaster, or pg_result.

Examples

if (FALSE) { # interactive()
priogrid::pg_set_rawfolder(file.path(tempdir(), "priogrid-example"))
temperature <- terra::rast(
  nrows = 18, ncols = 36,
  xmin = -180, xmax = 180, ymin = -90, ymax = 90,
  crs = "EPSG:4326", vals = 1:648
)
config <- priogrid::pg_config(nrow = 18, ncol = 36, verbose = FALSE)
pg_from_raster(
  temperature,
  variable = "temperature",
  aggregation = "mean",
  config = config
)
