An aerial and/or satellite imagery-based, optical system and corresponding method for measuring physical impacts to land-based objects by impact measurands in case of an occurrence of a natural catastrophe event, the natural catastrophe event impacting the objects causing a physical damage. The method and system comprise the steps of capturing by remote airborne and/or spaceborne sensors digital aerial and/or satellite imagery and/or photography of an area affected by the natural catastrophe event and generating a digital natural catastrophe event footprint with a topographical map of the natural catastrophe event based on the captured digital satellite imagery. Finally, parametrizing, by an adaptive vulnerability curve structure, impact measurands for selected objects based on the measured topographical map and generating an impact measurand value for each of the land-based objects based on an event intensity measured by the natural catastrophe event footprint using the vulnerability curve structure. In addition, the present invention leverages computer vision/deep learning/artificial intelligence on actual post catastrophe satellite and aerial imagery to detect and measure different types and/or damages of damage on properties/roofs.
