GDAL-RASTER-FILL-NODATA(1) GDAL GDAL-RASTER-FILL-NODATA(1)

gdal-raster-fill-nodata - Fill nodata values in a raster dataset

Added in version 3.11.

Usage: gdal raster fill-nodata [OPTIONS] <INPUT> <OUTPUT>
Fill nodata raster regions by interpolation from edges.
Positional arguments:

-i, --input <INPUT> Input raster dataset [required]
-o, --output <OUTPUT> Output raster dataset (created by algorithm) [required] Common Options:
-h, --help Display help message and exit
--json-usage Display usage as JSON document and exit
--config <KEY>=<VALUE> Configuration option [may be repeated]
--progress Display progress bar Options:
-f, --of, --format, --output-format <OUTPUT-FORMAT> Output format
--co, --creation-option <KEY>=<VALUE> Creation option [may be repeated]
--overwrite Whether overwriting existing output is allowed
-b, --band <BAND> Input band (1-based index) (default: 1)
-d, --max-distance <MAX_DISTANCE> The maximum distance (in pixels) that the algorithm will search out for values to interpolate. (default: 100)
-s, --smoothing-iterations <SMOOTHING_ITERATIONS> The number of 3x3 average filter smoothing iterations to run after the interpolation to dampen artifacts. The default is zero smoothing iterations. (default: 0)
--mask <MASK> Use the first band of the specified file as a validity mask (zero is invalid, non-zero is valid).
--strategy <STRATEGY> By default, pixels are interpolated using an inverse distance weighting (invdist). It is also possible to choose a nearest neighbour (nearest) strategy.. STRATEGY=invdist|nearest (default: invdist) Advanced Options:
--if, --input-format <INPUT-FORMAT> Input formats [may be repeated]


gdal raster fill-nodata fills nodata areas by interpolating from valid pixels around the edges of the area.

The following options are available:

Which output raster format to use. Allowed values may be given by gdal --formats | grep raster | grep + | sort

Output layer name.

Allow program to overwrite existing target file or dataset. Otherwise, by default, gdal errors out if the target file or dataset already exists.

Select an input <BAND> to be processed. Bands are numbered from 1. Default is the first band of the input dataset.

Specifies the maximum distance (in pixels) that the algorithm will search out for values to interpolate. Default is 100 pixels.

Specifies the number of smoothing iterations to apply to the filled raster. This can help to reduce artifacts in the filled areas. Default is 0 iterations.

Select the interpolation <STRATEGY> to use. By default, pixels are interpolated using an inverse distance weighting (invdist). It is also possible to choose a nearest neighbour (nearest) strategy.

Use the first band of the specified file as a validity mask (zero is invalid, non-zero is valid).

The command specifies to use the second band of the input raster, 50 px max distance, 3 smoothing iterations and the nearest strategy for interpolation. The output will be saved in output.tif.

gdal raster fill-nodata -b 2 --max-distance 50 --smoothing-iterations 3 \

--strategy nearest --mask mask.tif \
input.tif output.tif
