The next few months will take us to two corners of the world to meet with friends, collaborators, and new faces across the open geospatial community. Our team is getting ready to head to both FOSS4G North America in Reston, Virginia (November 3–5) and FOSS4G Global in Tāmaki Makaurau / Auckland, Aotearoa (November 17–23).

These gatherings are super important to us. FOSS4G is where ideas are shared openly, where projects grow through hallway conversations, and where the strength of the open geospatial movement is on full display.

E hara taku toa, I te toa takitahi, engari he toa taku tini

My strength is not from myself alone, but from the strength of many.

This whakataukī (proverb) shared at FOSS4G SotM Oceania 2023 captures why we keep showing up: our collective work moves faster, farther, and with greater impact when we build it together.

Why FOSS4G Matters

Our work depends on open infrastructure — tools, standards, and communities that make planetary-scale data accessible and usable. FOSS4G is where this ecosystem comes together: developers, scientists, governments, startups, humanitarian groups, and technologists all pulling the waka (boat) in the same direction.

These events are where we share what we’re building, learn from the brilliant work of others, and strengthen the relationships that make open geospatial sustainable. Whether it’s sprinting on new ideas, aligning around standards, or trading hard-earned lessons, FOSS4G is where the future of geospatial tech is shaped collaboratively.

And of course, we’ll also be bringing copies of our Optimizing Geospatial Data for the Cloud zine.

FOSS4G North America

Reston, Virginia, November 3-5, 2025

We’re kicking off the month stateside with talks and workshops focused on advancing cloud-native geospatial infrastructure. Our team will be leading and contributing to sessions on:

Workshop

Monday, 3 November

eoAPI: open-source cloud-native geospatial data cataloging and distribution
with Alex Mandel and Pete Gadomski
09:00-12:00 PM, Additional Fee, Pre-registration required.

We’ll have a table on site so come grab a zine, talk shop, or brainstorm new ways we can make geospatial data work better for everyone.

FOSS4G Global

Auckland, Aotearoa New Zealand, November 17–23

Two weeks later, we’re crossing the Pacific to join the global geospatial community in Tāmaki Makaurau/Auckland. This year, expect to hear a lot from us about Rust 🦀, and how modern, high-performance tooling can make geospatial work faster, more interoperable, and more open. We've got Kyle driving the message home with talks on GeoArrow, Obstore and Lonboard, showing you the latest advancements in processing and visualizing vector data at scale. Anthony will be giving a lightning talk on a Rust-based, Common Query Language (CQL2) parser teased recently in Groundwork 03, and Wei Ji will give a walkthrough on GeoTIFF decoding in Rust.

Presentations

Wednesday, 19 November

Faster, simpler access to cloud-based geospatial data with Obstore

Come say hi to our team. We'll be sharing copies of the Zine at our booth, and hacking on some Community sprint projects including a GeoRust code sprint over the weekend. All are welcome, whether you’re deep in the weeds of systems programming or just Rust-curious.

Let's Connect

FOSS4G is a celebration of the people and projects that make open geospatial work. We’re excited to share what we’ve been building, hear what you’ve been up to, and discuss what’s next together.

Stop by our sessions, find us at our tables, or catch us in the hallway — we’d love to connect.
