The bulk of my role at Schmidt Center for Data Science and Environment is leading the GeoJupyter project.

GeoJupyter community overview

---

GeoJupyter is an open and community-owned effort to reimagine geospatial interactive computing experiences within the Jupyter architecture to enable more people to confidently engage with geospatial data.

---

Many players!!!

GeoJupyter is not software; it’s a community which will build many things together!

GeoJupyter community overview

Geospatial data practice for the modern era

Geospatial data is everywhere and matters for everyone! 🚚🚢🗺️🧪🌏

🤝 Real-time collaboration (like Google Docs)

♻️ Reproducibility (by default!)

🍃 Accessibility (transition to new ways of working, including reproducibility)

☁️ Cloud-native (computing, data formats)

🤖 AI 😱 💥 (risks & opportunities)

GeoJupyter community overview

Open, participatory development

💞 User-centered & user-led

🤗 Welcoming (like Jupyter)

🔦 Exploring: finding & opening hidden doors

🏯 Data & computational sovereignty

🏗️ Projects in the GeoJupyter community

JupyterGIS

🤝 Collaborate

Two users collaborating in real-time on a JupyterGIS project (QuantStack)

Thanks again to the modular Jupyter architecture, we can leverage the jupyter-collaboration extension, which enables real-time collaboration on Notebooks, to enable real-time collaboration on a map.

Here you can see two users’ cursors (emphasized for visibility) on the same map.

🤝 Collaborate: Follow a user

In this graphic, one user is following another user’s viewport activity in real time.

🤝 Collaborate: Edit together

Two users editing a shared map (QuantStack)

Here you can see collaborators editing a shared map.

🤝 Collaborate: Annotations

Two users having a conversation with spatial context through annotations (QuantStack)

Here you can see collaborators having a spatially aware conversation, like comments in Google Docs.

🔮 Discover data with STAC (WIP)

Browsing a STAC catalog in JupyterGIS (eo science for society blog)

We can discover data using Spatio Temporal Asset Catalogs, or “STAC catalogs”, a modern standard for computer interface with data catalogs.

This is a work in progress that will continue to evolve over time!

Jupyter Tiler

Experiment: reproducible viz -> Notebook workflows

Reproducible workflow from viz-land to Notebook-land (👏 Benny & Esha!)

Future

📖 “Scrollytelling” (initiative)

🤖 GeoAI 🤔 (initiative, prototype, talk)

🪨 Richer geospatial primitives for Python (initiative)

⛰️ Reproducible “geoprocessing” (following lessons learned from interns’ exploration) (initiative)

🎨 Reusable symbology editor component? (initiative)

🧑‍🏫 Example datasets for education (initiative)

💭 Discussions &
💥 Demos

💥 💭 JupyterGIS

🐛 You might see bugs 🫣

uv run --with jupyterlab --with jupytergis jupyter lab

Or, even cooler…

💡 Launch from our docs (https://jupytergis.readthedocs.io) with JupyterLite - no installation and no signup required.

• Layer gallery (add basemap + chlorophyll)
• Add earthquakes layer
• Inspect data points
• Add france boundaries layer
• Compute convex hulls
• Grammar of graphics

💭 Reproducible viz -> Notebook workflows

Problem: Actions in visualization environments are often not reproducible

Awesome work by awesome interns

💥 💭 Roadmapping

Problem: Hard to track the many things going on and where we’re going next

Goal: Roadmapping as a forum, not a static output

Our “initiatives” GitHub repository

💥 💭 Contributor on-ramps

Problem: Contributors often ask us where they can get started, it helps to know who to talk to

Goal: Make it more intuitive for new community members to get started by self-serving (while building human connection with them)

Inspiration, Initiative, GitHub issue, PR, Preview
