Tracktable: Trajectory Analysis and Rendering

Hello! Welcome to the Tracktable documentation. Here you will find information and examples pretaining to the installation and usage of the Tracktable library.

Tracktable’s Purpose

Tracktable’s purpose is to load, assemble, analyze and render the paths traced out by moving objects. We combine the best tools and techniques we can find from both Python and C++ with the intent of making all of our capabilities easily accessible from both languages. Our goal is to make it easy to…

• Render trajectories as histograms (heatmaps), track plots and movies.

• Run heavy-duty analysis in C++ and manipulate the results quickly in Python.

• Couple algorithms from top to bottom:

  • Databases to store raw data

  • Perform filtering and cleaning techniques to assemble points into trajectories

  • Perform computational geometry to characterize trajectories

  • Clustering and spatial data structures to find groups

  • Visualization to help communicate findings

• Have fun!

Tracktable’s Target Audience

The target audience of Tracktable is individuals or teams that are interested in generating, analyzing and visualizing trajectories based on data generated by a variety of moving objects such as ships, airplanes and cars.
