batch_bandmath v 1.0 Program by Jonathan Greenberg This IDL program is designed to perform a band math statement on a large number of input files. It requires the user to keep a constant “prefix” for the input files corresponding to the bandmath bands (e.g. b1,b2, … bN). Inputs: A “band set” is a collection of equal spatial dimension files that are to be used in a band math statement. They are recognized by a shared prefix but differing suffixes, for instance: image01_band1.img and image01_band2.img The shared prefix is “image01” and the band suffixes are “_band1.img” and “_band2.img”. This algorithm is designed to batch process band sets. It’s a waste of time to use this if you only have one band set.
