raster (version 1.2-6)

resample: Resample

Description

Resample transfers values between non matching Raster* objects (in terms of origin and resolution). Avoid using this function if you can. Use functions like (dis)aggregate, crop and merge instead, because these functions are more accurate.

Usage

resample(from, to, method="ngb", filename="", ...)

Arguments

from

a Raster* object object

to

a Raster* object

method

method used to compute values for the new RasterLayer

filename

character. output filename

...

additional arguments. See Details.

Value

• A RasterLayer or RasterBrick object, and, in some cases, the side-effect of a file with the values of the new RasterLayer

Details

valid values for method are 'ngb' (nearest neighbor) and 'bilinear' (bilinear interpolation). The following additional arguments can be passed, to replace default values for this function rll{ overwrite Logical. If TRUE, "filename" will be overwritten if it exists format Character. Output file type. See writeRaster datatype Character. Output data type. See dataType progress Character. "text", "window", or "" (the default, no progress bar) }

Examples

r <- raster(nrow=3, ncol=3)
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)
