geojav-reykjanes-clip.mov

Submission to the Data Visualization and Effective Communication in Volcanology: Cross-disciplinary Lessons from Research and Practice collection in the Journal of Applied Volcanology.

Note

The geojav package does not contain production grade code. It is a proof-of-concept tool to help the paper authors easily explore the plume time-series datasets and collectively decide on the final static renders for submission.

Install

Please follow these steps to install the geojav package.

Clone the Repository

Make a local clone of the geovista-jav-2026 repository:

> git clone https://github.com/bjlittle/geovista-jav-2026
> cd geovista-jav-2026

Create the Environment

Create an environment to install geojav and all its required dependencies.

pixi 🧚

We recommend using pixi for package management.

Simply:

> pixi shell --environment geojav

Additionally, install direnv to activate/deactivate the geojav environment automatically whenever you enter/leave the geovista-jav-2026 directory:

> pixi global install direnv
> direnv allow

Tip

For information about the system, workspace and available pixi environments:

> pixi info

conda

Simply:

> conda env create --file requirements/geojav.yml
> conda activate geojav

Tip

Alternatively, for linux users only, install the fully resolved geojav environment:

> conda env create --file requirements/locks/geojav_linux-64_conda_spec.yml
> conda activate geojav

pip

Simply:

> pip install .
> pip install git+https://github.com/bjlittle/geovista.git@main

Warning

The PyPI package scitools-iris has a dependency on cf-units which in turn requires the Unidata UDUNITS-2 package (C based library) for units of physical quantities to be available.

The UDUNITS-2 package is not pip installable.
