The Free and Open Source Software for Geospatial (FOSS4G) conference series, hosted in partnership with OSGeo, brings together open source geospatial users, software developers, decision makers and researchers from around the world.
The FOSS4G 2025 conference in Auckland, New Zealand, will be a vibrant gathering that fosters collaboration and celebrates innovation in the exciting world of free and open source software for geospatial.
The event will feature workshops, technical sessions, keynote addresses, ‘lightning talks,’ code sprints and community events, social events and a ‘women in geospatial’ breakfast.
It is expected that the full program will be made available in August 2025.

The Positioning, Navigation and Timing 2026 (PNT2026) conference will be held at Sydney’s Royal Randwick Racecourse from 4 to 6 February next year.
Formerly known as the IGNSS Conference, PNT2026 will bring together local and global experts from industry, government, defence and academia to showcase and discuss the latest advancements in GNSS and alternative PNT technologies.
Key industry challenges will be on the agenda, as will applications across the aerospace, defence, smart city, autonomous systems and critical infrastructure sectors, and others.
This will be the first event of its kind since the International GNSS Association (IGNSS) merged with the Australian Institute of Navigation.
