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 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 GTiff – GeoTIFF File Format. Use the short format name.
