The Role of Orientation and Calibration in Photogrammetry and Remote Sensing: Preface to the European Calibration and Orientation Workshop - EuroCOW 2025

Abstract. This paper is a preface to the European Calibration and Orientation Workshop - EuroCOW 2025, held at the Warsaw University of Technology on 16–18 June 2025. The paper briefly introduces the history of EuroCOW workshops and shows orientation and calibration issues in photogrammetry and remote sensing based on the literature. The first part of the paper is a bibliographic analysis based on queries in the Scopus database, which shows a continuous interest in research activities based on calibration and orientation data, and the impact of those issues on communication channels, including the ISPRS Archives. The second part summarises abstract submissions presented during the workshop, showing their topics. The EuroCOW workshop was revived after a 6-year gap since its last organisation. This branded workshop has been organised by a dedicated working group of ISPRS and supported by EuroSDR for many years. Organisers hope that this activity will be continued in future.
