### New agenda items

- [Specta](https://github.com/trungleduc/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.
