ManagementThe author wants to focus on the importance of timely information during disaster as it facilitates decision making for the concerned authorities. These broadcast systems, especially similar to remote sensing, are cost-effective and have the best level of accuracy. Since the traditional method requires a lot of humanitarian efforts and there are chances of errors. While remote sensing uses give us broad multi-temporal coverage, they also image inaccessible and remote areas. The use of this technology allows us to predict the flood situation during or before the flood disaster. Space technology offers critical and synergistic potential towards developing the operational framework for space-based disaster management system. ISRO initiates several spaced programs to strengthen the disaster management system. To supplement and provide timely information to the affected region, a program such as Disaster Management Support (DMS) was initiated. Provides timely and accurate information. During the 2008 flood it monitored the entire area and provided timely information to the authorities concerned. The help of these technologies facilitates the evacuation process. About 30 satellites were used in the 2008 flood, including both microwave and optical satellites. These were used to map and monitor the scenario of the flood affected area in North Bihar. Cartosat-2 and IRS P6 LISS _iv MX were used to study river failure and inundation. The map showed the actual image on the surface of the ground while these images were further disseminated to the Ministry of Home Affairs, Central Water Commission, State Relief Commissioners. and Flood Management Information System and Patna Govt. as the concerned authorities have used this information for mitigation, relief and rescue activities to counter the impacts of disasters.
