gdal_fillnodata - Fill raster regions by interpolation from edges.

The 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.
- The script runs in quiet mode. The progress monitor is
suppressed and routine messages are not displayed.
- The maximum distance (in pixels) that the algorithm will
search out for values to interpolate.
- The number of 3x3 average filter smoothing iterations to
run after the interpolation to dampen artifacts. The default is zero
- Specify a special argument to the algorithm. Currently none
- -b band:
- The band to operate on, by default the first band is
- The source raster file used to identify target pixels. Only
one band is used.
- Do not use the default validity mask for the input band
(such as nodata, or alpha masks).
- Use the first band of the specified file as a validity mask
(zero is invalid, non-zero is valid).
- 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 GeoTIFF (GTiff).
Use the short format name.
