resample function

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 signature '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

Returns

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)
