gps for those w/o a gps

After my last post I spent some time dinking around on and playing with the gps visualizer (thanks to Atlanta Intown). The result? An elevation profile of Saturday's ride.

That's pretty cool. I have no idea how accurate it is, but it passes a test of interocular observation (it looks right).

GPS visualizer doesn't calculate total elevation gain (from what I can figure out), which is a major drawback, but I still think it's pretty cool.

Concentrate to the things that could give information to the people.

It's true that GPS Visualizer doesn't calculate total elevation gain/loss, for a simple reason: because GPS elevation data is so unreliable, the total would almost always be inaccurate. I'm not sure whether it's a good idea to add oft-requested information that I know is probably wrong!

If you want to calculate elevation gain/loss on your own, it'd be pretty easy to do in Excel after using GPS Visualizer's plain-text converter to put your data into tabular format.
