Welcome to Tracktable!

Tracktable is a set of Python and C++ libraries for the processing, analysis, and rendering of trajectory data. We define a trajectory as "a sequence of points with timestamps and a unique identifier".

Tracktable's main interface is a set of Python modules. Underneath that, we implement the core data structures and algorithms in C++ for speed and more efficient memory use. While you are welcome to work entirely in C++ if you prefer, we find it easier to use Tracktable in Python scripts and Jupyter notebooks.

For more information, please visit us at the Tracktable home page.

Getting Tracktable

Our main Git repository is at https://github.com/sandialabs/tracktable.git. We also upload Python wheels to PyPI so you can 'pip install tracktable' on most recent distributions.

If you choose to build from source, installation instructions are in the Git repository as part of the documentation.

Compatibility

Our development systems typically have the Anaconda Python distribution installed. However, there is nothing Anaconda-specific in our requirements or dependencies. We rely on Cartopy for rendering maps in Python as well as Pyshp for shapefile read/write support.

Using Tracktable

Our documentation is hosted at https://tracktable.readthedocs.org. We distribute Tracktable under a 3-clause BSD license whose text is included in the source distribution as well as on our web site.
