This book presents selected contributions from the 9th INGEO International Conference on Engineering Surveying, which will be held in Brno, Czech Republic, on October 15–17, 2025. The INGEO conference continues its tradition of bringing together professionals, researchers, and practitioners in the fields of civil engineering and engineering surveying to discuss the latest advances, innovative technologies, their applicability, and operational challenges. The event serves as an important international platform for the exchange of scientific knowledge, professional experience, and future perspectives in engineering geodesy.
