Kia ora! Last week, we were in Auckland, New Zealand, for FOSS4G 2025. We had a great time and gave four talks about various topics from GTFS to GeoArrow. Thanks so much to the organizers for putting on such a fantastic conference, and to everyone who came to our presentations!
For those who missed the talks, no worries——we share the slides in this post below. You can click the image to jump to the slides.
As you know, the next global FOSS4G conference, FOSS4G 2026, will be held in Hiroshima, Japan (30 Aug - 5 Sep, 2026). We are looking forward to welcoming you, as part of the broader Japanese geospatial community!
