Resample a Raster object

Resample transfers values between non matching Raster* objects (in terms of origin and resolution). Use projectRaster if the target has a different coordinate reference system (projection).

Before using resample, you may want to consider using these other functions instead: aggregate, disaggregate, crop, extend, merge.

# S4 method for class 'Raster,Raster'
resample(x, y, method="bilinear", filename="", ...)

Arguments

x

Raster* object to be resampled

y

Raster* object with parameters that x should be resampled to

method

method used to compute values for the new RasterLayer, should be "bilinear" for bilinear interpolation, or "ngb" for using the nearest neighbor

filename

character. Output filename (optional)

...

Additional arguments as for writeRaster

Value

RasterLayer or RasterBrick object

Examples

r <- raster(nrow=3, ncol=3)
values(r) <- 1:ncell(r)
s <- raster(nrow=10, ncol=10)
s <- resample(r, s, method='bilinear')
#par(mfrow=c(1,2))
#plot(r)
#plot(s)
