pad_raster

Description

Adding padding to raster

Usage

pad_raster(
  landscape,
  pad_raster_value,
  pad_raster_cells,
  global,
  return_raster,
  to_disk
)

## S3 method for class 'RasterLayer'
pad_raster(
  landscape,
  pad_raster_value = -999,
  pad_raster_cells = 1,
  global = FALSE,
  return_raster = TRUE,
  to_disk = getOption("to_disk", default = FALSE)
)

## S3 method for class 'RasterStack'
pad_raster(
  landscape,
  pad_raster_value = -999,
  pad_raster_cells = 1,
  global = FALSE,
  return_raster = TRUE,
  to_disk = getOption("to_disk", default = FALSE)
)

## S3 method for class 'RasterBrick'
pad_raster(
  landscape,
  pad_raster_value = -999,
  pad_raster_cells = 1,
  global = FALSE,
  return_raster = TRUE,
  to_disk = getOption("to_disk", default = FALSE)
)

## S3 method for class 'stars'
pad_raster(
  landscape,
  pad_raster_value = -999,
  pad_raster_cells = 1,
  global = FALSE,
  return_raster = TRUE,
  to_disk = getOption("to_disk", default = FALSE)
)

## S3 method for class 'list'
pad_raster(
  landscape,
  pad_raster_value = -999,
  pad_raster_cells = 1,
  global = FALSE,
  return_raster = TRUE,
  to_disk = getOption("to_disk", default = FALSE)
)

## S3 method for class 'matrix'
pad_raster(
  landscape,
  pad_raster_value = -999,
  pad_raster_cells = 1,
  global = FALSE,
  return_raster = FALSE,
  to_disk = getOption("to_disk", default = FALSE)
)

Arguments

landscape

Raster* Layer, Stack, Brick, SpatRaster (terra), stars, or a list of rasterLayers.
pad_raster_value

Value of cells added
pad_raster_cells

Number of rows and columns added
global

Only pad around the raster extent or also NA holes "inside"
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

Value

raster

Examples

pad_raster(landscape, pad_raster_value = -1, pad_raster_cells = 2)
