MovingPandas

Project Status: Active – The project has reached a stable, usable state and is being actively developed. build status docs status codecov DOI pyOpenSci

MovingPandas implements a Trajectory class and corresponding methods based on GeoPandas.

Visit movingpandas.org for details!

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

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

Installation

MovingPandas for Python >= 3.7 and all it's dependencies are available from conda-forge and can be installed using conda install -c conda-forge movingpandas.

Conda status

Conda Recipe Conda Downloads Conda Version Conda Platforms

Note that it is NOT recommended to install MovingPandas from PyPI! If you're on Windows or Mac, many GeoPandas / MovingPandas dependencies cannot be pip installed (for details see the corresponding notes in the GeoPandas documentation). On Ubuntu, pip install fails on cartopy with "Proj 4.9.0 must be installed".

Development Installation

Use the following steps to run the notebooks using the current development version:

Using conda

Linux/Mac:

conda env create -f environment.yml

Windows:

conda config --add channels conda-forge
conda config --add channels defaults
conda config --set channel_priority strict
conda env create -f environment.yml

On Windows, because conda-forge relies on some package built with defaults blas (like scipy) one must use the defaults channel on top of conda-forge and activate conda's new strict channel feature. Source: https://github.com/conda-forge/gdal-feedstock/issues/269#issuecomment-473661530

Using Anaconda

  1. Install Anaconda
  2. Clone the movingpandas repository
  3. In Anaconda Navigator | Environments | Import select the movingpandas environment.yml from the cloned directory:

image

  1. Wait until the environment is ready, then change to the Home tab and install Jupyter notebooks into the movingpandas environment
  2. Launch Jupyter notebooks and navigate to the movingpandas/tutorials directory to execute them
  3. Now you can run the notebooks, experiment with the code and adjust it to your own data

Known issues:

  • On Windows, importing rasterio can lead to DLL errors. If this happens, downgrade the rasterio version to 1.0.13.

Develop mode

To install MovingPandas in "develop" or "editable" mode you may use:

python setup.py develop

Related Python Packages

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).
