A Survey of Geomatics Solutions for the Rapid Mapping of Natural Hazards

摘要

Natural hazards demand a rapid assessment of the crisis situation and the use of Geomatics platforms, sensors and techniques can efficiently answer this need. Remotely sensed data can, in fact, provide a valuable source of broad scale information at each stage of the disaster management cycle, supporting scientists and authorities in the decision-making process. Geomatics-based procedures and techniques can be especially exploited in the emergency mapping domain for the extraction of reference (pre-event) and crisis (post-event) geographic data. The major challenges today concern the efficient selection (and integration) of the most fit-forpurpose mapping solution(s) and the development of automatic procedures to increase efficiency in data processing.
