13                       [-o name=value] [-b band]

DESCRIPTION

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