QGIS Processing Trajectools
The Trajectools plugin adds trajectory analysis algorithms to the QGIS Processing toolbox.
Requirements
Trajectools requires MovingPandas (a Python library for movement data analysis) and optionally integrates scikit-mobility (for privacy tests), stonesoup (for smoothing), and gtfs_functions (for GTFS data support).
Conda install
The recommended way to install these dependencies is through conda/mamba:
(base) conda create -n qgis -c conda-forge python=3.9
(base) conda activate qgis
(qgis) mamba install -c conda-forge qgis movingpandas scikit-mobility stonesoup
(qgis) pip install gtfs_functions(More details: https://anitagraser.com/2023/01/21/pyqgis-jupyter-notebooks-on-windows-using-conda/)
Pip install
If you cannot use conda, you may try installing from the QGIS Python Console:
import pip
pip.main(['install', 'movingpandas'])
pip.main(['install', 'scikit-mobility'])
pip.main(['install', 'stonesoup'])
pip.main(['install', 'gtfs_functions'])Plugin installation
The Trajectools plugin can be installed directly in QGIS using the built-in Plugin Manager:

Examples
The individual Trajectools algorithms are flexible and modular and can therefore be used on a wide array on input datasets, including, for example, the open Microsoft Geolife dataset a sample of which is included in the plugin repo:
