Damage assessment is a crucial aspect in different scientific but also publicly relevant fields. Especially in the humanitarian context the estimation is often time critical as conflict events, but also natural disasters urge a quick response. The presented approach analyzes the potential of cross-stereo satellite imagery, i.e. images from different dates of the same or even different satellite sensors, to allow the generation of pre- and post-event 3D information. The study area is located in the city of Mosul, Iraq. The concept of object-based analysis was applied for the 3D damage assessment. The classification outcomes are categorized in four different height classes. 73 % of the point reference data matches with the classification results of the damage assessment.
