GIGASAR is a project funded by the European Space Agency (ESA) to develop new methods for precise infrastructure monitoring. It combines high-resolution Synthetic Aperture Radar (SAR) data, Building Information Modeling (BIM) and additional geoinformation with AI-based methods to detect movements in the subsurface and in structures at an early stage and with a high degree of reliability. The aim is to develop market-ready services for European clients from industry and public administration.<\/strong><\/p>\n\t<\/div>\r\n<\/div>\r\n\r\n\r\n\r\n

In the GIGASAR project, the Research Center of Post-Mining (FZN) at the Technische Hochschule Georg Agricola in Bochum, together with EFTAS (M\u00fcnster)<\/strong><\/a>, is investigating how various high-resolution satellite radar datasets can be combined with digital building models and additional geodata into an integrated analysis approach. The focus is on how deformations and changes in infrastructure and urban spaces can be detected more precisely than with existing methods.<\/p>\n

For this purpose, multi-frequency SAR data, including Sentinel-1, TerraSAR-X, and PALSAR-2, are combined with structural information on buildings and infrastructure as well as modern AI methods. This is intended to enable the reliable detection and assessment of both large-scale deformation processes and local changes affecting individual objects such as buildings, roads, bridges, or utility networks.<\/p>\n

A key feature of the project is its consistent focus on practical application. GIGASAR is not only a research and development project but is explicitly aimed at creating commercially usable and scalable services for European users. The methods developed are being validated under real-world conditions in two test areas \u2013 a building complex in Bochum and an urban area in Ahlen.<\/p>\n

In addition, a European stakeholder platform is being established to connect research, public administration, and industry. Workshops, training courses, and scientific publications are intended to help make the project results widely available and support their use in future European services.<\/p>\n\t<\/div>\r\n<\/div>\r\n\r\n\r\n\r\n\n\t\t\t<\/div> \n\t\t<\/div>\n\t<\/div> \n<\/div><\/div>\n\t\t
