gdal_fillnodata1
Fill raster regions by interpolation from edges.
Usage
gdal_fillnodata [--help] [--help-general] [-q] [-md <max_distance>]
[-si <smoothing_iterations>] [-o <name>=<value> [<name>=<value> ...]]
[-mask <filename>] [-interp {inv_dist,nearest}] [-b <band>]
[-of <gdal_format>] [-co <name>=<value>]
<src_file> <dst_file>
Overview
gdal_fillnodata 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.
TIP:
Equivalent in new "gdal" command line interface:
See gdal raster fill-nodata.
NOTE:
gdal_fillnodata is a Python utility, and is only available if GDAL Python bindings are available.
-
--help -
Show this help message and exit
-
--help-general -
Gives a brief usage message for the generic GDAL commandline options and exit.
-
-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. The default is 100 pixels.
-
-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.
-
-mask <filename> -
Use the first band of the specified file as a validity mask (zero is invalid, non-zero is valid).
-
-of <format> -
Select the output format. The default is GTiff -- GeoTIFF File Format. Use the short format name.
-
-interp {inv_dist,nearest} -
Added in version 3.9.
By default, pixels are interpolated using an inverse distance weighting (
inv_dist). It is also possible to choose a nearest neighbour (nearest) strategy.
<srcfile>-
The source raster file used to identify target pixels. Only one band is used.
<dstfile>-
The new file to create with the interpolated result.
Return status code
The program returns status code 0 in case of success, and non-zero in case of error (non-blocking errors emitted as warnings are considered as a successful execution).
