South Australia’s Spatial Information Day (SID) will be held on Friday, 7 August at the Adelaide Convention Centre.
An annual highlight of the South Australian geospatial community’s calendar, SID brings together experts from the fields of surveying, GIS, remote sensing, photogrammetry and more, for wide-ranging discussions and networking.
The theme for 2026 is ‘Every future starts somewhere: From ground truth to space, shaping what comes next,’ and for 2026 the organisers are hoping to attract around 400 delegates and 40 speakers. This year will also see the introduction of the inaugural South Australian EISSI Awards Dinner.
The call for abstracts and papers is now open, with speakers invited to submit their ideas within a wide span of topics, such as:
- Various spatial disciplines, e.g. GIS, surveying and so on;
- Real-world case studies;
- Insights into innovation techniques and approaches;
- Smart cities and infrastructure;
- Emerging technologies.
A sponsorship prospectus is now available, while tickets for the event are expected to go on sale soon.

The 10th International Colloquium on Scientific and Fundamental Aspects of GNSS will bring together members of the European scientific community and international partners involved in the use of Galileo and other GNSS in their research.
The colloquium will address several major areas of research:
- Scientific applications in meteorology, geodesy, geodynamics, geophysics, space physics, oceanography, land surface and ecosystem studies;
- Scientific developments in physics with a potential impact on future GNSS, particularly in testing fundamental laws of physics;
- Aspects of metrology such as reference frames, on board and ground clocks, precise orbit determination and time and frequency transfer; and
- Scientific aspects of satellite navigation, positioning and its applications, such as signal propagation, precise positioning;
The conference will be organised as a series of plenary talks, parallel half day sessions and poster presentations.
