This is a very cool site/tool for GPS users. “MotionBased is a web application that translates GPS data into functional analysis and online mapping for endurance and outdoor athletes.” (Geocachers, too!) 😆 You can upload your GPS tracks and designate the type of activity. It gives you stats on your trip. It even goes to the Web to retrieve weather data for your location and time during the trip. Here’s a sample of one of my tracks:

So far I’ve found it to be much easier to use than importing tracks into Google Earth and it gives you more ways to look at the data.
