make tiles from a raster

Description

split a raster in a number of same size tiles

Usage

make_tiles(
  r,
  ncol = 2,
  nrow = 2,
  path = NULL,
  sufix = "tile_",
  format = ".tif",
  datatype = "FLT4S"
)

Arguments

r	SpatRaster
ncol	number of vertical divisions
nrow	number of horizontal divisions
path	folder to save tiles
sufix	sufix to be add to filename
format	format of file to be saved
datatype	type of data (byte, integer, float). Values for datatype are "INT1U", "INT2U", "INT2S", "INT4U", "atatype = "FLT4S"atatype = "FLT4S"", "FLT4S", "FLT8S". The first three letters indicate whether the datatype is integer (whole numbers) of a real number (decimal numbers), the fourth character indicates the number of bytes used (allowing for large numbers and/or more precision), and the "S" or "U" indicate whether the values are signed (both negative and positive) or unsigned (positive values only).

Value

SpatRaster
