Organised by OSGeo, this international annual gathering of location enthusiasts is the largest global gathering for geospatial software. Now in its 15th year, FOSS4G (ie. Free and Open Source Software for Geospatial) brings together developers, users, decision-makers and observers from a broad spectrum of organisations and fields of operation.
Through six days of workshops, presentations, discussions, and cooperation, FOSS4G participants create effective and relevant geospatial products, standards, and protocols. The 2021 event will be focused for the first time on South America and will be held with the close collaboration of the GeoLibres Association in Buenos Aires, Argentina.

Featuring a spotlight on crowd-sourced bathymetry, the Map the Gaps Symposium 2023 will bring people together to learn, share and contribute to ocean discovery.
Held on behalf of GEBCO, this event draws global experts in ocean technology, science and policy to discuss deep and coastal ocean exploration, offshore surveying technology, policy, diversity, equity and inclusion, the Nippon Foundation-GEBCO Seabed 2030 project and GEBCO alumni activities.
Participation is open to all, including industry professionals, explorers, authors, students, researchers, government representatives and emerging technologists. Participants can attend in person or online.

BeGeo, an initiative of the Belgian National Geographical Institute (NGI), is an annual national event for the geo sector in Belgium.
The BeGeo conference combines with a geographic information fair to bring together a wide range of players from the public sector, academia, research, the private sector and associations. This year, the organisers have once again chosen Brussels Expo as the location for the event.
BeGeo says its vision is to be a platform where important players from the sector meet and thus actively contribute to the growth of the knowledge and competences necessary to tackle complex challenges and realise the great potential of geodata.

The ISPRS Technical Commission II ‘Photogrammetry’ focuses, at various scales, on geometric, radiometric and multi-temporal aspects of the image- and range-based 3D surveying, mapping and modelling in the age of AI and mixed reality.
The organisers of the June 2024 Symposium welcome researchers, practitioners and companies involved in photogrammetry and computer vision to present and discuss their results with a broader audience. The Symposium will feature four days of plenary and keynote talks, along with parallel sessions of oral and poster presentations from academia and industry.
The symposium’s theme is ‘The Role of Photogrammetry for a Sustainable World,’ emphasising machine learning and mixed reality. The event is being organised in collaboration with ASPRS (American Society of Photogrammetry and Remote Sensing) and SGPF (Swiss Society of Photogrammetry and Remote Sensing).
