aggregate_raster: Downscale raster resolution

In jscamac/edmaps: Estimate Likelihood of Pest Establishment

Downscale raster resolution

Description

Aggregate raster cells (and optionally layers) to coarser resolution.

Usage

aggregate_raster(
  rast,
  outfile,
  aggregate_factor,
  fun = sum,
  return_rast = FALSE
)

Arguments

rast	Raster* object or file path to a raster file.
outfile	Character. Output raster file path. If not provided, object will be returned to R. Directory will be created recursively if it does not exist.
aggregate_factor	Integer. Aggregation factor expressed as number of cells in each direction (horizontally and vertically). Or a vector of two integers (horizontal and vertical aggregation factors) or three integers (when also aggregating over layers).
fun	Function. Function used to aggregate values. Default is sum.
return_rast	Logical. Should the resulting raster be returned to R? Ignored if outfile is not provided.

Value

If outfile is specified, the resulting raster is saved as a geotiff to that path. If return_rast is TRUE or outfile is not specified the resulting raster is returned, otherwise NULL is returned invisibly.
