There are lots of different possibilities of GPS data viualizations. For your joy I have put together a not comprehensive list of examples. The variety is striking and so is the range of software, although oft I have not been able to find out how it is done. Different examples of GPS data visualizations is a list of animations but also a list of approaches. Some animations have featured earlier on this blog, other are new, as the intention is to show variety and not completeness. If you have some good examples yourself or know of some, please post in the comment and this showcase of examples will grow lager, contact can be found here.
