NAME

       r.resample  - GRASS raster map layer data resampling capability.

KEYWORDS

       raster, resample

SYNOPSIS

       r.resample
       r.resample help
       r.resample [-q] input=string output=string  [--overwrite]  [--verbose]  [--quiet]

   Flags:
       -q
           Quiet

       --overwrite
           Allow output files to overwrite existing files

       --verbose
           Verbose module output

       --quiet
           Quiet module output

   Parameters:
       input=string
           Name of an input layer

       output=string
           Name of an output layer

DESCRIPTION

       r.resample  resamples  the  data  values  in a user-specified raster input map layer name (bounded by the
       current geographic region and masked by the current mask), and produces a new  raster  output  map  layer
       name  containing  the  results of the resampling.  The category values in the new raster output map layer
       will be the same as those in the original, except that the resolution and extent of the new raster output
       map layer will match those of the current geographic  region  settings  (see  g.region).   r.resample  is
       intended  for  reinterpolation of continuous data to a different resolution rather than for interpolation
       from scattered data (use the v.surf.* modules for that purpose).

NOTES

       The method by which resampling is conducted is  "nearest  neighbor"  (see  r.neighbors).   The  resulting
       raster  map  layer  will have the same resolution as the resolution of the current geographic region (set
       using g.region).

       The resulting raster map layer may be identical to the original raster map layer.  The r.resample program
       will copy the color table and history file  associated  with  the  original  raster  map  layer  for  the
       resulting  raster  map  layer and will create a modified category file which contains description of only
       those categories which appear in resampled file.

       When the user resamples a GRASS reclass file, a true raster map is created by r.resample.
