Before getting the Delorme Topo USA software, I tried that - but a bunch of places, the numbers made no sense. I would check a place right along the beach and it would say I was 20 or more feet high! Even over the ocean - you know, like SEA LEVEL - it would say I was well above that. Places that I knew should be going downhill would show increasing elevation!
