NAME
gdal_fillnodata - gdal_fillnodata.py 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.
