3D disaster management a study on utilization of smart CCTV-based 3D geo-spatial information

Today, frequently occurring natural disasters not only cause large-scale damage but are also difficult to predict because of the complexity of factors. Therefore, economic damages and casualties caused by natural disasters are gradually increasing. However, disaster-management measures are unable to be adapted rapidly enough to respond to fast-changing disasters. According to rapid responders, one of the most important elements of disaster management is secured prime time. However, the current disaster management system cannot identify the exact disaster area and its surroundings because of the lack of a situation propagation system. Therefore, we need to establish new disaster management measures. The government has made efforts to predict disaster situations and minimize damages; however, this is difficult because of the lack of situational awareness about the disaster area; it cannot support effective decision-making.
