Command line raster calculator with numpy syntax.

Synopsis --calc=expression --outfile=out_filename [-A filename]
             [--A_band=n] [-B...-Z filename] [other_options]


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

-A <filename>

Input gdal raster file, you can use any letter (A-Z).


Number of raster band for file A (default 1).


Output file to generate or fill.


Output nodata value (default datatype specific value).


Output datatype, must be one of [Int32, Int16, Float64, UInt16, Byte, UInt32, Float32].


GDAL format for output file.


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.

Add two files together: -A input1.tif -B input2.tif --outfile=result.tif --calc="A+B"

Average of two layers: -A input.tif -B input2.tif --outfile=result.tif --calc="(A+B)/2"

Set values of zero and below to null: -A input.tif --outfile=result.tif --calc="A*(A>0)" --NoDataValue=0
