New AI makes satellite data understandable – can speed up crisis decision-making
22.5.2026 08:00:00 CEST | Umeå University | Press Release
Large volumes of environmental data are collected today, but much of it remains unused. Now, Arka Ghosh at Umeå University has developed an AI solution that makes complex data from satellite images and weather maps directly usable for decision-makers.
The system, called Ontoraster, links each pixel in images to an intelligent network where data gains clear meaning and can be analysed together with other information. By combining knowledge graphs and AI, users can ask advanced questions and receive fast, comprehensible answers.
"It is an advanced AI solution that could be highly valuable for urban planners as well as crisis and emergency coordinators, says Arka Ghosh," PhD student at Umeå University.
The technology can, for example, identify risk areas during heatwaves or floods and thereby support faster and more accurate decisions. It also enables people without a technical background to use advanced data analysis.
"What previously required extensive manual analysis can now be done in seconds," says Arka Ghosh.

3D printers can make advanced research more accessible5.10.2026 08:00:00 CEST | Press Release
Developing new research equipment is often expensive and time-consuming. In his doctoral thesis, Daniel Nilsson at Umeå University demonstrates how standard 3D printers can be used to rapidly manufacture advanced scientific instruments directly in the laboratory.
Researchers discover major ecological shift in the Gulf of Bothnia2.10.2026 10:00:00 CEST | Press Release
For decades, scientists have regarded phosphorus as the main nutrient limiting biological production in the Gulf of Bothnia. Now, a new study led by researchers at Umeå University shows that a fundamental change is underway. The Bothnian Sea has shifted to nitrogen limitation, while the Bothnian Bay is rapidly moving in the same direction.
