landscapemetrics (version 2.1.4)

pad_raster: pad_raster

Description

Adding padding to raster

Usage

pad_raster(
  landscape,
  pad_raster_value = -999,
  pad_raster_cells = 1,
  global = FALSE,
  return_raster = TRUE,
  to_disk = getOption("to_disk", default = FALSE)
)

Value

raster

Arguments

landscape

A categorical raster object: SpatRaster; Raster* Layer, Stack, Brick; stars or a list of SpatRasters.

pad_raster_value

Value of cells added

pad_raster_cells

Number of rows and columns added

global

If TRUE, NAs within the landscape are replace with the value; if FALSE only padding around the raster is added.

return_raster

If false, matrix is returned

to_disk

Logical argument, if FALSE results of get_patches are hold in memory. If true, pad_raster writes temporary files and hence, does not hold everything in memory. Can be set with a global option, e.g. option(to_disk = TRUE).

Details

Adds equally (in all four directions) additional cells around the raster

Examples

landscape <- terra::rast(landscapemetrics::landscape)
pad_raster(landscape, pad_raster_value = -1, pad_raster_cells = 2)
