Date Posted: 12:25:57 02/12/04 Thu In reply to: Pathfinder 's message, "Re: National Geographic TOPO Software" on 21:22:31 02/10/04 Tue Well, I got it and am really impressed. I have aways been a map nut. I have tons of topo quads, have downloaded a lot more, have way too many computer mapping programs... I also spent a while last night upgrading the firmware on the GPS from version 1.05 to 3.15... never know you could do that. This program is pretty powerful especially with the GPS funcionality... The best part is that my waypoints from LSPP are now saved for eternity and show up on the outline of the coast. I have already printed my own coyote camp expedition map. This is cool... Let me know if you need a team cartographer... ak >>When using a GPS, how accurate are the fixes based on >>real world location? > >As long as you use the same map datum for the GPS and >Map, they are pretty accurate.
