15
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.
