gdal_fillnodata - Fill raster regions by interpolation from
edges.
gdal_fillnodata [--help] [--help-general] [-q] [-md <max_distance>]
[-si <smoothing_iterations>] [-o <name>=<value> [<name>=<value> ...]]

gdal_fillnodata 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.
NOTE:
gdal_fillnodata is a Python utility, and is only
available if GDAL Python bindings are available.
- --help
- Show this help message and exit
- --help-general
- Gives a brief usage message for the generic GDAL commandline options and
exit.
- -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.
- -mask
<filename>
- Use the first band of the specified file as a validity mask (zero is
invalid, non-zero is valid).
- -of <format>
- Select the output format. The default is GTiff -- GeoTIFF File
Format. Use the short format name.
- -interp
{inv_dist,nearest}
- New in version 3.9.
By default, pixels are interpolated using an inverse distance
weighting (inv_dist). It is also possible to choose a nearest
neighbour (nearest) strategy.
- <srcfile>
- The source raster file used to identify target pixels. Only one band is
used.
- <dstfile>
- The new file to create with the interpolated result.
