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.

-q:

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

-md max_distance:

The maximum distance (in pixels) that the algorithm will search out for values to interpolate.

-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.

-nomask:

Do not use the default validity mask for the input band (such as nodata, or alpha masks).

-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 GeoTIFF (GTiff). Use the short format name.
