Sydney is putting itself forward as a host city for the 2030 International Society for Photogrammetry and Remote Sensing Congress, one of the world’s leading gatherings for photogrammetry, remote sensing and spatial information science. If successful, the bid would bring the global geospatial community to Australia at a time when Earth observation, digital twins, GeoAI and location intelligence are becoming essential tools for solving complex environmental, infrastructure and resilience challenges.

A bid grounded in place, purpose and collaboration

The Sydney bid is being led by prominent geospatial experts Petra Helmholz and Sisi Zlatanova, with Locus Alliance serving as the host organisation. Its theme, “Caring for Earth and People: Past Wisdom, Future Vision,” positions the Congress as more than a technical event. It frames geospatial science as a bridge between knowledge systems, communities and practical action for a more sustainable future.

That message is reinforced by the bid identity, Nakiliko malang, meaning “see together”. The visual concept reflects Sydney as a gathering place where sky, land and water meet, and where different ways of seeing the world can be brought into conversation. It is a fitting idea for a Congress dedicated to technologies that help societies observe, interpret and understand the planet at many scales.

Why Sydney makes a compelling host city

Australia has long been active in the fields that define ISPRS: photogrammetry, LiDAR, remote sensing, Earth observation analytics, GeoAI and spatial information science. National-scale initiatives such as Digital Earth Australia demonstrate how analysis-ready satellite data can support environmental monitoring and disaster response, while the NSW Spatial Digital Twin shows how integrated 3D and 4D spatial data can inform planning, emergency management and urban resilience.

Hosting the Congress in Sydney would give international delegates direct access to this applied innovation ecosystem. It would also place the event in the Indo-Pacific, a region where climate adaptation, coastal resilience, disaster preparedness, sustainable urban growth and land management are urgent priorities. For researchers, industry partners, governments and students, Sydney could offer a highly relevant setting for exchanging ideas that move from science to implementation.

A Congress with global relevance

The 2030 Congress would arrive at a significant moment for the geospatial sector. Advances in sensors, automation, cloud platforms and artificial intelligence are rapidly changing how spatial data is collected, processed and used. At the same time, decision-makers need trusted geospatial information to address increasingly interconnected challenges, from biodiversity loss and water security to infrastructure risk and humanitarian response.

In that context, Sydney’s bid theme feels especially timely. “Caring for Earth and People” recognises that geospatial technologies are not only about measurement and modelling; they are also about responsibility. “Past Wisdom, Future Vision” invites a broader conversation about how scientific innovation can sit alongside cultural knowledge, local experience and long-term stewardship.

Building on Australia’s ISPRS legacy

Australia has hosted the ISPRS Congress before, most recently in Melbourne in 2012 under the theme “Imaging a Sustainable Future”. Bringing the Congress back to Australia in 2030 would continue that legacy while highlighting how much the field has evolved. The emergence of digital twins, operational Earth observation platforms and AI-enabled geospatial analysis gives the next Australian-hosted Congress the potential to showcase both scientific progress and real-world impact.

Looking ahead

The decision on the 2030 host city is expected to be made at the ISPRS Congress in Toronto. Sydney is one of several international destinations bidding for the honour, making the process a strong reflection of the global reach and ambition of the ISPRS community.

Whatever the outcome, Sydney’s bid makes a powerful case for the role of geospatial science in shaping a more resilient and informed future. By bringing together technical excellence, cultural perspective and a commitment to practical impact, the bid captures what the ISPRS Congress is ultimately about: seeing the world more clearly, together.
