resample.Rd
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 extent of the input and output are the same, you should consider using these other functions instead: aggregate
, disagg
, extend
or crop
.

SpatRaster to be resampled
SpatRaster with the geometry that x
should be resampled to
character. Method used for estimating the new cell values. One of:
near
: nearest neighbor. This method is fast, and it can be the preferred method if the cell values represent classes. It is not a good choice for continuous values. This is used by default if the first layer of x
is categorical.
bilinear
: bilinear interpolation. This is the default if the first layer of x
is numeric (not categorical).
cubic
: cubic interpolation.
cubicspline
: cubic spline interpolation.
lanczos
: Lanczos windowed sinc resampling.
sum
: the weighted sum of all non-NA contributing grid cells.
min, q1, med, q3, max, average, mode, rms
: the minimum, first quartile, median, third quartile, maximum, mean, mode, or root-mean-square value of all non-NA contributing grid cells.
logical. If TRUE
multiple threads are used (faster for large files)
character. Output filename
additional arguments for writing files as in writeRaster
