Dear community, I want to subset a stacked image (e.g. 4,1000,1000 dimensions) in IDL with widget_subset in ENVI. My problem is that the header of the subset (incl. UTM coordinates) does not exist after the export of the subset. The exported subset does not contain a header. How can I read out the correct header from the subseted image (likewise to the ENVI_DOIT, 'ENVI_LAYER_STACKING_DOIT')? Thanks for your answers, Michael Wiesner
