Charlie, this sounds like an excellent solution - potentially much less 
involved than the old way of using MicroDem and the USGS website.  If 
you can provide a few more details, I'll be glad to write it up, and I'd 
bet that N6BV and the ARRL will be interested in making it available on 
the ARRL web-site.  Dean and I wrote most of the old instructions you'll 
find, but it always was a PITA because USGS kept changing their web-site.
