I’ve recently been lamenting the lack of a good tool for viewing time-series GPS data. I couldn’t find a nice way to, for example, compare a series of runs, or show a series of events on a map. So, I’ve started writing a library to do that. Currently it’s very basic, but as there’s more functionality I want, I’ll add more stuff to it. At the moment, its main use (for me) is comparing runs from different days to see how they compare, but I hope to add the ability to display richer information.
