NAME
gdal_fillnodata - Fill raster regions by interpolation from edges.
SYNOPSIS
gdal_fillnodata.py [-q] [-md max_distance] [-si smooth_iterations]
[-o name=value] [-b band]
srcfile [-nomask] [-mask filename] [-of format] [dstfile]
DESCRIPTION
gdal_fillnodata.py script fills selection regions (usually nodata ar-
eas) by interpolating from valid pixels around the edges of the area.
Additional details on the algorithm are available in the GDALFillNo-
data() docs.
-q The script runs in quiet mode. The progress monitor is sup-
pressed and routine messages are not displayed.
-md max_distance
The maximum distance (in pixels) that the algorithm will search
out for values to interpolate. The default is 100 pixels.
-si smooth_iterations
The number of 3x3 average filter smoothing iterations to run af-
ter 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.
-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 raster.gtiff. Use the
short format name.
