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 Numpy Stuff: http://www.scipy.org/Numpy_Example_List#head-7eb5ca476fca411db1db64bc024b7c0c94e42143 Regards On 20 December 2011 10:11, Stephen Mather <[email protected]> wrote: > Hi All, > Is there any casting (for lack of a better word) needed when using > gdal_calc to take, e.g. a series of 16-bit images and perform float > functions against them? > > Best, > Steve > > _______________________________________________ > gdal-dev mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/gdal-dev _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
