DESCRIPTION

14       The gdal_fillnodata.py script fills selection regions (usually nodata
15       areas) by interpolating from valid pixels around the edges of the area.
16
17       Additional details on the algorithm are available in the
18       GDALFillNodata() docs.
19
20       -q:
21           The script runs in quiet mode. The progress monitor is suppressed
22           and routine messages are not displayed.
23
24       -md max_distance:
25           The maximum distance (in pixels) that the algorithm will search out
26           for values to interpolate.
27
28       -si smooth_iterations:
29           The number of 3x3 average filter smoothing iterations to run after
30           the interpolation to dampen artifacts. The default is zero
31           smoothing iterations.
32
33       -o name=value:
34           Specify a special argument to the algorithm. Currently none are
35           supported.
36
37       -b band:
38           The band to operate on, by default the first band is operated on.
39
40       srcfile
41           The source raster file used to identify target pixels. Only one
42           band is used.
43
44       -nomask:
45           Do not use the default validity mask for the input band (such as
46           nodata, or alpha masks).
47
48       -mask filename:
49           Use the first band of the specified file as a validity mask (zero
50           is invalid, non-zero is valid).
51
52       dstfile
53           The new file to create with the interpolated result. If not
54           provided, the source band is updated in place.
55
56       -of format:
57           Select the output format. The default is GeoTIFF (GTiff). Use the
58           short format name.
