Preview Hi folks - I'm a bit of a newbie programmer with IDL and especially, with incorporating ENVI calls into IDL. I have what I think is a simple question - I am trying to write a relatively simple IDL procedure/function that will call ENVI functions. We need this to be a quick, streamlined program (so we do not want the GUI/ENVI interface overhead). I need to create 60 ROI's for my application emanating from a single point. The catch in, the point can be anywhere in my input raster, and I only know it's location in UTM coordinates. I need to know its location in x,y, so I can define my ROI's. I'd like the simplest solution to finding this UTM defined location in raster space, without, for instance, having to go through the particulars of the UTM projection definition. Surely there is some easy way to have ENVI/IDL 'tell' me where tihs point is in raster x,y coordinates? I can't seem to figure this out. I am running IDL 7.0 and ENVI 4.5. Thanks! Cyndy
