FOSS4G 2025 will be held from 17th - 23rd November 2025, Auckland, New Zealand.

We are pleased to open our Call for Presentations and Workshops. FOSS4G brings geospatial professionals, software developers and users from around the globe, for 5 days of workshops, talks and activities. We welcome all levels of expertise, from highly technical to end user, and from academic, professional and community projects, on subjects related to Free and Open Source GIS, Open Street Map, and publication and use of open data.

There are four available formats:

• Presentations – full talks are limited to 20 minutes of content with 5 minutes for questions. Presentations are delivered in the General Sessions over the main conference days Wednesday Nov 19th, Thursday Nov 20th and Friday Nov 21st.

• Lightning Talks – lightning talk sessions are rapid presentations strictly limited to 5 mins. Lightning talks are presented back-to-back with several other speakers, and provide a good opportunity to share smaller projects, anecdotes or lighthearted content in an informal session.
