[gdal-dev] How to-- gdal_calc.py

[Travis Kirstine]

Stephen,

I haven't used the gdal_calc tool but if you use python you can easily
convert the image bands to a set of numpy arrays and use all the
great numpy functions.

See the val_repl.py  sample to convert a image to a numpy array(s)
http://svn.osgeo.org/gdal/trunk/gdal/swig/python/samples/val_repl.py
