MovingPandas

MovingPandas is a Python library for movement data exploration and analysis.

MovingPandas provides trajectory data structures and functions for handling movement data based on Pandas, GeoPandas, and HoloViz.

Visit movingpandas.org for details!

You can run MovingPandas examples on MyBinder - no installation required: (These examples use the latest MovingPandas release version.)

To try the cutting-edge dev version, use this MyBinder link.

Documentation

We recommend starting your MovingPandas journey with the tutorial notebooks on the official homepage

The official API documentation is hosted on ReadTheDocs

Examples

Trajectory plots

Create interactive trajectory plots using Folium and Geoviews with ease

Including multiple linked plots

For all types of tracking data, e.g. video-based trajectories

Including plots in custom projections

Stop detection

Detect stops in trajectories, extract them as points or segments, and use them to split trajectories

Trajectory generalization

Generalize trajectories using spatial, temporal, and spatiotemporal methods

Trajectory cleaning & smoothing

Clean and sooth trajectories by removing outliers and applying Kalman filters

Trajectory aggregation

Aggregate trajectories to explore larger patterns

Installation

MovingPandas for Python >= 3.9 and all its dependencies are available from conda-forge and can be installed using

conda install -c conda-forge movingpandas

or faster using

mamba install -c conda-forge movingpandas

Note that it is NOT recommended to install MovingPandas from PyPI! If you are using Windows or Mac, many GeoPandas / MovingPandas dependencies may not install correctly with pip (for details see the corresponding notes in the GeoPandas documentation). On Ubuntu, pip install may fail, e.g. on cartopy with "Proj 4.9.0 must be installed".

Development installation

Use the following steps to install MovingPandas in "develop" or "editable" mode and run the notebooks using the current development version:

conda env create -f environment.yml
pip install --editable .

scikit-mobility is a similar package which also deals with movement data. It implements TrajectoryDataFrames and FlowDataFrames on top of Pandas instead of GeoPandas. There is little overlap in the covered use cases and implemented functionality (comparing MovingPandas tutorials and scikit-mobility tutorials). MovingPandas focuses on spatio-temporal data exploration with corresponding functions for data manipulation and analysis. scikit-mobility on the other hand focuses on computing human mobility metrics, generating synthetic trajectories and assessing privacy risks. Plotting is based on Folium.

Traja extends the capabilitis of Pandas DataFrames specific for animal trajectory analysis in 2D. Plots (static) are based on seaborn.

PyMove provides functionality similar to MovingPandas. It implements PandasMoveDataFrames and DaskMoveDataFrame on top of Pandas and Dask DataFrames. Plotting is based on Folium.

Tracktable is a related Python package with its core data structures and algorithms implemented in C++, i.e. it is not based on Pandas. Plotting is based on Cartopy (for still images) and Folium (for interactive rendering).
