gdal_fillnodata(1)gdal_fillnodata(1)NAMEgdal_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
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 suppressed
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.
