New agenda items¶

• Specta stuff

  • Story maps!

    • Hooks in to Specta’s “presentation” mode, and in that case renders the story viewer instead of the regular JupyterGIS interface.

  • Mobile view.

    • Detects Specta in “presentation” mode, and if the screen is small renders differently.

  • Can also write e.g. a blog post as a Notebook, with JupyterGIS widgets, and view in Specta’s blog post view

  • TODO: Add to Lite deployment in docs of JupyterGIS

  • TODO: Tutorial on story map, how to use Specta

• Layer gallery improvements!

  • More types supported, not just raster

  • Simpler representation in the JSON

• jupyter-xarray-tiler

  • https://github.com/geojupyter/jupyter-xarray-tiler

  • Problem: Have to write out xarray datasets to file to visualize

    • Solution: TiTiler / xpublish-tiles!

  • Problem: Running a tile server in a kernel, and running a map visualizer in browser JS means sometimes you can’t access the tile server, e.g. JupyterLab running in a kubernetes pod (JupyterHub) without exposed ports.

    • Solution: jupyter-server-proxy!

  • jupyter-xarray-tiler is just glue between jupyter-server-proxy, titiler (and eventually other backends like xpublish-tiles), and a mapping front-end. It’s aimed at authors of map viz libraries for Jupyter, not end-users.

  • Martin: What about other formats than Xarray? Zarr?

    • Matt: Have been thinking about GeoDataFrames as well. Should we bundle that in the same library? :thinking_face: Maybe? I don’t know. In any case I’m totally fine with changing the name if we go that route :)

    • Matt: xpublish-tiles supports Zarr. But not TiTiler AFAIK. There’s a few options now for directly visualizing Zarr from OpenLayers (e.g. https://github.com/NOC-OI/zarr-maps) as well. Do we need a solution like this for Zarr? :thinking_face:

• mambajs: Generate notebook.link lockfiles from CLI!

  • https://pypi.org/project/mambajs/

  • Previously needed to be done from the notebook.link web UI, now we can build it in to our automated tooling.
