Description
The gdal2xyz utility can be used to translate a raster file into xyz format. gdal2xyz can be used as an alternative to gdal_translate of=xyz, but supporting other options, for example:
Select more then one band
Skip or replace nodata value
Return the output as numpy arrays.
- --help
Show this help message and exit
- --help-general
Gives a brief usage message for the generic GDAL commandline options and exit.
- -skip
How many rows/cols to skip in each iteration.
- -srcwin <xoff> <yoff> <xsize> <ysize>
Selects a subwindow from the source image for copying based on pixel/line location.
- -b, -band <band>
Select band band from the input spectral bands for output. Bands are numbered from 1 in the order spectral bands are specified. Multiple -b switches may be used. When no -b switch is used, the first band will be used. In order to use all input bands set -allbands or -b 0.
- -allbands
Select all input bands.
- -csv
Use comma instead of space as a delimiter.
- -skipnodata
Exclude the output lines with nodata value (as determined by srcnodata)
- -srcnodata
The nodata value of the dataset (for skipping or replacing) Default (None) - Use the dataset nodata value; Sequence/Number - Use the given nodata value (per band or per dataset).
- -dstnodata
Replace source nodata with a given nodata. Has an effect only if not setting -skipnodata. Default(None) - Use srcnodata, no replacement; Sequence/Number - Replace the srcnodata with the given nodata value (per band or per dataset).
- -h, --help
Show help message and exit.
- <src_dataset>
The source dataset name. It can be either file name, URL of data source or subdataset name for multi-dataset files.
- <dst_dataset>
The destination file name.
Examples
gdal2xyz -b 1 -b 2 -dstnodata 0 input.tif output.txt
To create a text file in xyz format from the input file input.tif, including the first and second bands, while replacing the dataset nodata values with zeros.
