Finessing traverses with TopoFusion and Google Earth

On my previous posts, you may have noticed that the tracks including stints on the backroads, streets, and highways. Rarely are those of any value in my geologic mapping efforts. I am really only interested in the foot traverses most of the time.

It is also nice to eliminate the fluff to know how far you have walked and the elevation gain and loss if not just to compensate for a week away from the gym or the bike (or if not just to feel good about yourself as you descend into middle-age). As I was lamenting the unneeded data in my traverse files, I remembered TopoFusion--an excellent program for editing the tracklogs to their essential parts. It also provides and nice profile analysis tool with an intuitive and flexible animation / visualization utility. I know that this type of feature has great potential for completing my map when integrated with notes, geotagged photos, and random recollections. Maybe I can boil it down into a useful post or two.

Once I trimmed the traverses to their relevant parts, I used TopoFusion to learn that I walked nearly 20 miles over the last 4 days and climbed and descended more than 10,000 ft. in all. Turns out that most field work on foot with a moderately heavy pack, occasional heart-racing encounters with snakes and cool outcrops, and a swim in the lake adds up to some decent exercise. More reasons to be a field geologist...and maybe part of the reason they / we seem to live so long...

Check TopoFusion out. The free version is practically enough, but the paid versions do have some options you will ultimately want. I have barely scratched the surface on the various options and applications.
