Interactive widgets for topographic data analysis and modelling in Jupyter notebooks.

While ipyfastscape is tightly integrated with fastscape, it also integrates very well with any data in the form of an xarray dataset or any model created with xarray-simlab.

The widgets available here are built on top of libraries of the jupyter's widget ecosystem such as ipywidgets and ipygany. You can reuse those high-level UI components as-is within notebooks (embedded mini-apps) or for building interactive dashboards that you can then publish as standalone web applications (using voil).


  • TopoViz3d: Paraview-like 3D terrain visualization, with time player and dimension explorer

  • AppLinker: Easily link different application instances for, e.g., side-by-side comparison


You can install ipyfastscape either with conda:

$ conda install ipyfastscape -c conda-forge

or using pip:

$ python -m pip install ipyfastscape

If you use jupyterlab (2.x), you also need to install some extensions:

$ jupyter labextension install @jupyter-widgets/jupyterlab-manager ipygany

If you installed ipyfastscape using pip and you are using jupyter's "classic" notebook, you need to enable those extensions:

$ jupyter nbextension enable --py --sys-prefix ipygany
