I posted about this the other day, but I've still been playing with it, and I had new test data.
I went mountain biking. Here's the route I took today as recorded with my GPS receiver, as drawn by Google Earth:
Map
That's in Annadel State Park, near Santa Rosa, CA
Google Earth doesn't provide a certain feature I want though, which is elevation profiling, and total vertical climbing distance, so I wrote a program to create graphs like this:
Graph
The end of that graph is missing. It should descend back to the same elevation as I started at (the location of my car), but I crashed on the way down the hill, and apparently the crash caused my GPS to turn itself off. Must have bumped the power switch or something.
The one part with the vertical line preceeded by a short flat spot is due tothe GPS losing tracking, and then getting a signal again at the point where the elevation jumps up.
