mosaic: mosaic SpatRasters

Description

mosaic SpatRasters to form a new SpatRaster object with a larger spatial extent. Unlike with merge, values on overlapping areas are averaged.

Usage

# S4 method for SpatRaster,SpatRaster
mosaic(x, y, ..., fun="mean", filename="", overwrite=FALSE, wopt=list())

Arguments

x

SpatRaster

y

object of same class as x

...

additional SpatRasters

fun

character. One of "sum", "mean", "median", "min", "max"

filename

character. Output filename. Optional

overwrite

logical. If TRUE, filename is overwritten

wopt

list. Options for writing files as in writeRaster

res(y) <- res(x)
values(x) <- 1:ncell(x)
values(y) <- 1:ncell(y)
