Analyzing GPS Track Data

In a previous post, I talked about one of my favorite web sites for converting and viewing your GPS track data, called GPS Visualizer. Now I want to introduce you to another web tool that can analyze your track data, called, conveniently enough, Analyze My Track. As stated on the home page, this nifty little tool evaluates gpx logs from your GPS device and provides the following information back:
  • reverse geocoding: track points labeled with names of nearby features;
  • maps: view your track on Google Maps;
  • stats: distance, elevation, speed and time;
  • graphs: interactive elevation/speed/distance;
In the words of my kids, "it's way cool". Here's an example of what some of the results look like, using GPS track data from a geocaching / bike ride I did just this morning:

This is the first page you see after the web application calculates various statistics from your track data.

The tool also provides you with different interactive graphs as well as some Google Maps showing certain aspects of your tracks.

Here's part of the Google Maps map it created showing my route, color-coded by elevation (using a green to red color gradient):

And here's the elevation profile it provided:

The tool also gives you a speed vs. distance graph as well. Give it a try when you get a chance.

Cache On!
