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 2025 Pacific GIS & Remote Sensing User Conference will be held in Suva, Fiji, from 24 to 29 November.

This is the largest annual GIS and remote sensing event held within the Pacific Island community, regularly bringing together more than 300 experts from government, academia and industry for five days of presentations and workshops.

The event will also include nightly social functions that will enable participants to relax and network in informal settings.

The conference is organised by the Pacific GIS and Remote Sensing Council.

Geo Week 2026 will bring together geospatial and mapping professionals to explore how data, maps, and advanced technologies can deepen our understanding of the world and inform solutions to complex challenges.

Designed for decision-makers and problem-solvers, the conference program will feature case studies, expert panels and roundtable discussions for the canvassing of ideas and predictions from a variety of experts: innovators, end-users, regulators and others.

The associated exhibition will showcase the latest solutions for the geospatial sector and the built world one roof, including BIM, advanced airborne/terrestrial technologies, and commercial 3D technologies.

The Australasian Hydrographic Society’s (AHS) internationally recognised hydrographic conference program will return in 2026, beginning with the Hydrospatial 2026 Conference.

The conference will be held from 23 to 26 March 2026 at Shed 6 in Wellington, New Zealand.

With a theme of ‘Shaping the Future of Marine Discovery,’ the event will bring together professionals and thought leaders from across government, defence, research, industry and academia to explore the evolving role of hydrography.

The four-day program will feature keynote speakers, technical sessions, panel discussions, exhibitions, and networking opportunities across six key themes:

• Advances in hydrographic technology and autonomous systems
• Blue Economy and sustainable maritime development
• Coastal infrastructure, ports and harbour innovation
• Climate change, oceanography and marine environmental science
• Law of the Sea, sovereignty and maritime domain awareness
• Hydrospatial data for marine policy, planning and heritage

Further details of the event will be posted on the conference website and also on the Society’s website during the coming months.

Sydney Build is Australia’s largest construction and design show, held every year at the International Convention Centre at Darling Harbour in the heart of Sydney.

The event attracts 25,000-plus attendees and 550-plus speakers across 15 stages, as well as 600-plus exhibitors. There also are networking parties, a government hub and an architect’s hub.

Themes will include:

• AI and digital construction
• Sustainability
• Diversity, inclusion and reconciliation
• The future of housing
• Health and safety
• Architecture and design

The International Society for Photogrammetry and Remote Sensing’s (ISPRS) XXV Congress will be held in Toronto, Canada, from 4 to 11 July 2026. This will be the first ISPRS Congress to held in Canada since the event in Ottawa in 1972, so it will be an historic occasion.

The event will bring together researchers, practitioners and industry leaders from around the globe to explore the latest advancements, trends and applications in photogrammetry and remote sensing.

The theme of the Congress, From Imagery to Understanding, captures the role of ISPRS and its scientific activities, and will culminate in a legacy project to create materials that can be used by the ISPRS community to better promote to funding agencies and others the important role that it plays in the world’s economic and environmental activities.

The Congress will run in parallel with the 47th Canadian Symposium on Remote Sensing (CSRS).

The abstract submission deadline has been extended to 17 November 2025, and early bird registration is now available.
