JupyterGIS sync meeting 2025-05-06

A weekly gathering of JupyterGIS team to discuss our progress and help each other out. Open to all, but this meeting is short and task-focused, so there will not be time for introductions. Please join a core meeting!

Status reports

• Matt: CNG went well! Prepping for a workshop next week, won’t be doing much dev.
• Arjun:
  • Settings PR: https://github.com/geojupyter/jupytergis/pull/619
  • Schema version PR: https://github.com/geojupyter/jupytergis/pull/590
    • Should the field be under “metadata” or at the root?
    • ipynb has “nbformat” and “nbformat_minor” both at the root.
      • Notebook metadata has information about the kernel, that’s it.
      • Maybe JGIS projects have “author”, “last_edited” as metadata. What else?
      • What about viewport location? Currently in options, which we think makes sense. That’s the project data.
      • Decision: Keep schema_version at the root!
    • What about annotations? Should they be metadata or top-level?
      • Matt/Greg: Gut says top-level, but we can leave as-is for now.
  • Annotation UX improvements: https://github.com/geojupyter/jupytergis/pull/650 , https://github.com/geojupyter/jupytergis/pull/640
• David:
  • TiTiler extension: https://github.com/geojupyter/jupytergis-tiler
    • Serve zarr file https://github.com/geojupyter/jupytergis-tiler/blob/main/examples/xarray.ipynb
    • Does this enable collaboration on a Xarray DataArray?
      • Depends. if the Kernel is shared by everyone, it should work!
      • If JupyterLite, no go.
    • Adds new dependency, makes the doc a bit more complex.
    • Not sure whether this belongs in core yet. David feels strongly not to! Martin feels adding to core could be nice.
    • Serve non-optimized GeoTIFFs from kernel.
