SYNOPSIS

gdal_calc.py [-A <filename>] [--A_band] [-B...-Z filename] [other_options]
Options:
-h, --help show this help message and exit
--calc=CALC calculation in gdalnumeric syntax using +-/* or any
numpy array functions (i.e. logical_and())
-A A input gdal raster file, note you can use any letter
A-Z
--A_band=A_BAND number of raster band for file A (default 1)
--outfile=OUTF output file to generate or fill
--NoDataValue=NODATAVALUE
set output nodata value (Defaults to datatype specific
value)
--type=TYPE output datatype, must be one of ['Int32', 'Int16',
'Float64', 'UInt16', 'Byte', 'UInt32', 'Float32']
--format=FORMAT GDAL format for output file (default 'GTiff')
--creation-option=CREATION_OPTIONS, --co=CREATION_OPTIONS
Passes a creation option to the output format driver.
Multiple options may be listed. See format specific
documentation for legal creation options for each
format.
--allBands=ALLBANDS process all bands of given raster (A-Z)
--overwrite overwrite output file if it already exists
--debug print debugging information

DESCRIPTION

Command line raster calculator with numpy syntax. Use any basic arithmetic supported by numpy arrays such as +-*\ along with logical operators such as >. Note that all files must have the same dimensions, but no projection checking is performed.

EXAMPLE

add two files together

gdal_calc.py -A input1.tif -B input2.tif --outfile=result.tif --calc="A+B"

average of two layers

gdal_calc.py -A input.tif -B input2.tif --outfile=result.tif --calc="(A+B)/2"

set values of zero and below to null

gdal_calc.py -A input.tif --outfile=result.tif --calc="A*(A>0)" --NoDataValue=0
