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.

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.
