FOSS4G 2025
We are excited to welcome everyone to FOSS4G 2025 in Auckland, New Zealand, from 17–23 November
This year’s conference offers a unique opportunity for both newcomers and regular attendees to immerse themselves in the world of open geospatial. Participants can make friends, meet some heroes, explore a diverse selection of presentations and hands-on workshops, and celebrate the things we do with open geospatial.
With plenty of opportunities and a variety of social events, FOSS4G 2025 is the perfect occasion to experience the fun and collaborative spirit of open source! And Aotearoa/New Zealand is a wonderful country in the South Pacific with heaps of stuff to do before or after the conference, so bring the family and call it a holiday/vacation!
The event is proudly supported by Auckland University of Technology’s School of Future Environments and will be held at the AUT City Campus in the heart of Auckland. This central location is just minutes from the business district, offering excellent public transport links and a wide range of accommodation options.
