gpxsplitter splits multi-track GPX files, containing waypoints, into individual one-track GPX files with their respective waypoints.
GPX files containing multiple tracks and waypoints jumbled together are produced by many GPS units, in particular MTK chipset-based devices such as the Qstarz Q1000 and Transystem i-Blue 474 devices. Separating tracks and their associated waypoints was a headache until gpxsplitter came along.
gpxsplitter depends on the Python 2.6 (or above in the 2.x series) and the modules:
- lxml
- mxDateTime
On Debian/Ubuntu, you can install the required dependencies with:
sudo aptitude install python-lxml python-egenix-mxdatetime
At some point, I'm going to refactor gpxsplitter to not need mxDateTime and depend on ElementTree in Python's stdlib, so script can work on Python 3.
Download gpxsplitter.py directly, or browse the gpxsplitter repository on Gitorious.

Benchmarks
Very informal testing:
Program |
Time |
gpxsplit |
24s |
gpxmgr |
32s |
gpxsplitter |
1s |
Other programs
I found a few pre-existing programs that perform the same, or similar function:
gpxsplit is a Haskell/Haxml-based GPX file splitter. On Ubuntu, required some 360 MB of dependencies (Haskell compilers, libraries, etc).
gpxmgr is a Python/minidom-based GPX file splitter. Python's minidom is known for being notoriously slow.
As you can see in Benchmarks, gpxsplitter is significantly faster, and requires fewer dependencies.
