makeTiles: Make tiles

In terra: Spatial Data Analysis

Make tiles

Description

Divide a SpatRaster into "tiles". The cells of another SpatRaster (normally with a much lower resolution) or a SpatVector with polygon geometry can be used to define the tiles. You can also provide one or two numbers to indicate the number of rows and columns per tile.

Usage

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

Arguments

x	SpatRaster
y	SpatRaster, SpatVector, or numeric
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
overwrite	logical. If TRUE, existing tiles are overwritten; otherwise they are skipped (without error or warning)
...	additional arguments for writing files as in writeRaster

Value

character (filenames)

Examples

r <- rast(ncols=100, nrows=100)
values(r) <- 1:ncell(r)
x <- rast(ncols=2, nrows=2)
filename <- paste0(tempfile(), "_.tif")
ff <- makeTiles(r, x, filename)
