(not talking about pan-sharpening, but in general,) how about the situation where you have a map data which is loudly dominated by a signal, and you want to try and remove that loud signal so that you can look at the subtle variations caused by a different source that the loud signal had been masking? is removing PC1 then back-inverting a suitable method for that sort of task? or is there another more suitable method? thanks, Hamish _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
