A toolbox for processing and analysing air traffic data

The traffic library helps working with common sources of air traffic data.

Its main purpose is to offer basic cumbersome data analysis methods commonly applied to trajectories and ATC sectors. When a specific function is not provided, the access to the underlying structure is direct, through an attribute pointing to a pandas dataframe.

The library also offers facilities to parse and/or access traffic data from open sources of ADS-B traffic like the OpenSky Network or Eurocontrol DDR files. It is designed to be easily extendable to other sources of data.

Static visualisation (images) exports are accessible via Matplotlib/Cartopy. More dynamic visualisation frameworks are easily accessible in Jupyter environments with ipyleaflet and altair; or through exports to other formats, including CesiumJS or Google Earth.

Installation

Latest release:

pip install --upgrade traffic

Development version:

pip install git+https://github.com/xoolive/traffic

Warning: cartes and shapely have strong dependencies to dynamic libraries which may not be available on your system by default.

Before reporting an issue, please try to use an Anaconda environment. Other installations (You may check them in the .travis.yml configuration file.) should work but the Anaconda way proved to work smoothly.

conda install cartopy shapely

For troubleshootings, refer to the appropriate documentation section.

Tests and code quality

tests Code Coverage Codacy Badge Checked with mypy

Unit and non-regression tests are written in the tests/ directory. You may run pytest from the root directory.

Tests are checked on Github Actions platform upon each commit. Latest status and coverage are displayed with standard badges hereabove.

In addition, code is checked against static typing with mypy (pre-commit hooks are available in the repository) and extra quality checks performed by Codacy.

Command line tool

The traffic tool scripts around the library for common usecases.

The most basic use case revolves around exploring the embedded data. You may check the help with traffic data -h.

traffic data -p Tokyo
     altitude country iata  icao   latitude   longitude                                name

Feedback and contribution

Any input, feedback, bug report or contribution is welcome.

Should you encounter any issue, you may want to file it in the issue section of this repository. Please first activate the DEBUG messages recorded using Python logging mechanism with the following snippet:

import logging
logging.basicConfig(level=logging.DEBUG)

Bug fixes and improvements in the library are also helpful.

If you share a fix together with the issue, I can include it in the code for you. But since you did the job, pull requests (PR) let you keep the authorship on your additions. For details on creating a PR see GitHub documentation Creating a pull request. You can add more details about your example in the PR such as motivation for the example or why you thought it would be a good addition. You will get feedback in the PR discussion if anything needs to be changed. To make changes continue to push commits made in your local example branch to origin and they will be automatically shown in the PR.

You may find the process troublesome but please keep in mind it is actually easier that way to keep track of corrections and to remember why things are the way they are.

Frequently asked questions

Join the chat at https://gitter.im/xoolive/traffic

  • I want to know more about Eurocontrol NM files

We download these files from Eurocontrol Network Manager Demand Data Repository (DDR) under Dataset Files > Airspace Environment Datasets. Access conditions are managed by EUROCONTROL.

Should you have no such access, basic FIRs are provided in eurofirs from traffic.data.

  • I want to know more about Eurocontrol AIXM files

When you import aixm_airspaces from traffic.data, you need to set a path to a directory containing AIRAC files. These are XML files following the AIXM standard and produced by Eurocontrol. We download these files from Eurocontrol Network Manager B2B web services. You have to own a B2B certificate granted by EUROCONTROL to get access to this data.

  • What does AIRAC mean?

Aeronautical Information Publications are updated every 28 days according to fixed calendar. This cycle is known as AIRAC (Aeronautical Information Regulation And Control) cycle.
