Letter Re: Free GPS Topographical Map Software and Adjuncts

Maps are something I have a lot of fun with. I wrote up a blog post on free online mapping centered around topographical maps that if you haven’t already encountered these tools you might find it interesting. In a post at Gear Addicts, I cover how to acquire free topographical maps, as well as using the topo maps in conjuncture with programs like Google Earth, and NASA World Wind. Making a free and in some ways superior replacemnt for expensive software by National Geographic and Garmin. Regards, – Grant
