Natural Disaster Management Study by Review of Topographical Features Using Satellite Imagery

Natural Disasters are the events occurred within the earth system that leads to death or injury to humans and damage of valuable goods like buildings, communication systems, agricultural land, forest, natural environment. Natural disasters can be easily identified and the cause and effect of it can be minimized by the satellite image analysis. Satellite image analysis plays an essential role for environment and climate monitoring. Image classification is an essential process for performing the digital image examination in an efficient way. In satellite image classification process the grouping of image pixel values into pre-defined classes is done. Many satellite image classification methods were introduced for performing efficient disaster management. The analysis of two different problems is carried out in this paper to improvise the efficiency of determining the disaster management using satellite imagery.
