DESCRIPTION

38       r.resample resamples the data values in a user-specified  raster  input
39       map  layer name (bounded by the current geographic region and masked by
40       the current mask), and produces a new raster output map layer name con‐
41       taining  the results of the resampling.  The category values in the new
42       raster output map layer will be the same  as  those  in  the  original,
43       except  that  the  resolution  and  extent of the new raster output map
44       layer will match those of the current geographic region  settings  (see
45       g.region).
46

NOTES

48       The  method by which resampling is conducted is "nearest neighbor" (see
49       r.neighbors).  The resulting raster map layer will have the same  reso‐
50       lution  as  the  resolution of the current geographic region (set using
51       g.region).
52
53       The resulting raster map layer may be identical to the original  raster
54       map  layer.   The r.resample program will copy the color table and his‐
55       tory file associated with the original raster map layer for the result‐
56       ing  raster  map  layer  and will create a modified category file which
57       contains description of only those categories which appear in resampled
58       file.
59
60       When the user resamples a GRASS reclass file, a true raster map is cre‐
61       ated by r.resample.
