JupyterGIS sync meeting

🙏 Our apologies, there’s no time for introductions!

We’re excited for you to join us, but this meeting is short and task-focused. Please attend community meetings (see GeoJupyter calendar) to meet the team and add your own agenda items, and/or introduce yourself on Zulip!

Status reports¶

• Grammar of graphics

  • PR merged!

    • Bug: When radius not set, nothing is displayed.

  • Martin: Working on Python API side! geojupyter/jupytergis#1420

    • Expose grammar of graphics on the programmatic API! 🎉

    • Factory functions for e.g. constant_color

    • Can pass multiple factory functions as a list, and these are separate symbology “layers” (we need a better name for this!)

    • Objects with chainable methods, e.g. constant_num(3, target=["circle-radius", "circle-stroke-width"]).color_ramp(value="mag", target="stroke", name="viridis")

    • Race condition: sometimes symbology doesn’t apply as expected.

• Matthias: Vega-lite plot rendering PoC (geojupyter/jupytergis#1419)

  • Matt: Mixed feelings about mixed plot and map symbology in the UI! More efficient, but potentially confusing. Some icons for which mappings are plot mappings and which are map ones might be useful! (👍 Martin)

  • Matt: What do we think this UI should look like?

    • Bottom panel right now, reusing same space as console.

    • Might be nice to use different JLab tabs

      • Should be doable if they are lumino widgets, Lab will allow drag-and-drop. Could then also generate plots in notebooks!

      • Can use similar approach for attribute tables

    • Floating might also be nice!

    • Ability to name plots!

  • Testing symbology with OpenLayers

    • Matt: Snapshot testing? Or?

• OpenEO support

  • Available from the Python API on main geojupyter/jupytergis#1287

  • UI Components to edit the OpenEO layer in progress geojupyter/jupytergis#1409

• GeoZarr support in progress geojupyter/jupytergis#1400

  • Remains to get the symbology to work with it (needs to get the bands info from the zarr file lazily) 💯
