NAME

       gdal_fillnodata - Fill raster regions by interpolation from edges.

SYNOPSIS

          gdal_fillnodata.py [-q] [-md max_distance] [-si smooth_iterations]
                          [-o name=value] [-b band]
                          srcfile [-nomask] [-mask filename] [-of format] [dstfile]

DESCRIPTION

       gdal_fillnodata.py  script fills selection regions (usually nodata areas) by interpolating
       from valid pixels around the edges of the area.

       Additional details on the algorithm are available in the GDALFillNodata() docs.

       -q     The script runs in quiet mode. The  progress  monitor  is  suppressed  and  routine
              messages are not displayed.

       -md max_distance
              The  maximum  distance (in pixels) that the algorithm will search out for values to
              interpolate. The default is 100 pixels.

       -si smooth_iterations
              The  number  of  3x3  average  filter  smoothing  iterations  to  run   after   the
              interpolation to dampen artifacts. The default is zero smoothing iterations.

       -o name=value
              Specify a special argument to the algorithm. Currently none are supported.

       -b band
              The band to operate on, by default the first band is operated on.

       srcfile
              The source raster file used to identify target pixels.  Only one band is used.

       -mask filename
              Use  the  first  band  of  the  specified file as a validity mask (zero is invalid,
              non-zero is valid).

       dstfile
              The new file to create with the interpolated result.  If not provided,  the  source
              band is updated in place.

       -of format
              Select the output format. The default is raster.gtiff.  Use the short format name.
