Multimedia Data Management for Disaster Situation Awareness
نویسندگان
چکیده
To raise awareness in disaster situations, the quality and analysis of disaster-related big data are essential. Recent developments in the collection, analysis, and visualization of multimedia data have led to a significant enhancement in disaster management systems. Crowdsourcing tools, for instance, allow citizens to perform an active role in reporting information relevant to disaster events at a global scale through popular social media sites such as Twitter and Facebook. As multimedia data analysis becomes further advanced, it can augment the disaster situation awareness and provide an efficient and timely response. This paper describes how multimedia data management plays a prominent role in improving the capabilities to readily manage disaster situations. Specifically, visualization provides a more convenient and user-friendly means for individuals who have limited experience in disaster situations. A case study introducing a 3D animation system is presented, which simulates the impacts of storm surge near coastal areas.
