Description Usage Arguments Value See Also Examples

Description

resample transfers values between SpatRaster objects that do not align (have a different origin and/or resolution). See project to change the coordinate reference system (crs).

If the origin and crs are the same, you should consider using these other functions instead: aggregate, disaggregate, expand or crop.

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

Arguments

x

SpatRaster to be resampleed

y

SpatRaster that x should be resampled to

method

character. Method used for estimating the new cell values. One of:

near: nearest neighbour. This method is fast, and the preferred method if the cell values represent classes. It is not a good choice for continuous values.

bilinear: bilinear interpolation. Default.

cubic: cubic interpolation.

cubicspline: cubic spline interpolation.

lanczos: Lanczos windowed sinc resampling.

filename

character. Output filename

...

additional arguments for writing files as in writeRaster

Value

SpatRaster
