STREAMLINE
Rod, I use Adobe Streamline together with Corel. It's a dynamite
combination! Streamline even has a menu option for generation of output
explicitly compatible with Corel Draw (in .AI format).
As for scanning maps, I haven't tried that. But from my experience, you'll
probably have little trouble with outlining areas, a bit more trouble
getting things like roads and cities. Abandon the thought of getting usable
text off a map. I suggest you clean the text off the map when its still in
bitmap form (you should really have some kind of bitmap editor if you're
going to be scanning artwork for use with Streamline; perhaps the one that
came with your scanner, if any, is good enough) then add the text back once
the artwork is in Corel Draw.
