Natural calamity assessment by innovative methods

摘要

The earth is a dynamic entity that is undergoing changes all the time. However, sometimes the forces of nature cause great and drastic changes, and human beings and the effect can be disastrous. Though these disasters cannot be stopped, their damages can be minimized with proper management measures. To take up effective management and effective measures, there has to be efficient disaster assessment. Assessment is a vital component of the planning and implementation of the response to disasters. The phrase disaster assessment refers to the investigation and data collection activities carried out to conclude the outcome of disaster and area of disaster hit area. Here, we propose an algorithm that uses satellite images for assessing the disaster impact. The satellite images of flood affected region are collected from BHUVAN (ISRO), while data for fire affected region is collected from NASA associated official web source. We have compared our results with the government records to validate our proposed methodology. Accuracy is calculated and compared with conventional methods.
