Make tiles

Description

Divide a SpatRaster into "tiles". The cell of another SpatRaster (normally with a much lower resolution) are used to define the tiles.

Usage

## S4 method for signature 'SpatRaster'
makeTiles(x, y, filename="tile_.tif", extend=FALSE, na.rm=FALSE, ...)

Arguments

x	SpatRaster
y	SpatRaster or SpatVector
filename	character. Output filename template. Filenames will be altered by adding the tile number for each tile
extend	logical. If TRUE, the extent of y is expanded to assure that it covers all of x
na.rm	logical. If TRUE, tiles with only missing values are ignored
...	additional arguments for writing files as in writeRaster

Value

character (filenames)
