Hack teams¶

For ideas, check out the hackathon and good first issue labels on the JupyterGIS project!

Join the corresponding breakout room to hack!

1. Add to / improve architecture documentation: geojupyter/jupytergis#576. (Martin, Sanjay, Kristin)
   • Review PR
   • Keep in mind that code gets outdated quickly, and thus documentation of it can as well. Can make descriptions in the documentation more high-level so we can avoid documentation getting out-of-date quickly.
2. Remove Source Panel geojupyter/jupytergis#435 👍 (Martin) 👍 (Arjun) - geojupyter/jupytergis#671
3. Simplify Symbology Panel - geojupyter/jupytergis#469 👍 (Arjun; Martin & Kristin joined later in the hackathon)

Didn’t work on today:

• Make Python package builds more self-contained: geojupyter/jupytergis#585 i) Try implementing dev environment with pixi?
• Annotations as a dataset / create vector data: geojupyter/jupytergis#395
• Continue evolving a reproducible “processing toolbox” model: geojupyter/jupytergis#519

Share out¶

Think about: What exciting things did you accomplish? What loose ends remain? Big questions? Big ideas?

• Simplify Symbology Panel - geojupyter/jupytergis#469
  • Need to keep discussing this
  • Perhaps could use a style function? See example from OpenLayers
  • Bring Greg into the conversation
    • He has an example of a style function in mainView.tsx
      • The style applies to everything - doesn’t look for the layer type
  • Maybe remove SimpleSymbol.tsx, and define all prefixes (lines 94 - 98) for all different types
  • Perhaps need to change circle-fill-color argument to something more generic, like color-, and then have a way for the software to know how to apply that to different geometry types
• Arjun removed the source panel! Still has to remove some related styles - geojupyter/jupytergis#671
• Martin, Sanjay, Kristin worked on architecture documentation and completed a revised draft - geojupyter/jupytergis#576
