NAME

       gdal_calc - gdal_calc.py Command line raster calculator with numpy syntax

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 0)
         --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
