gdal_fillnodata - Man Page
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. 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.
- srcfile
The source raster file used to identify target pixels. Only one band is used.
- -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.
