Abstract

The impacts of change ever have been remained great consideration after the occurrence of natural disasters so it might be detected the expected hazard, vulnerability and risk for taking mitigative measures in future. This study has been done based on utilizing the two different date's satellite imageries in that context. The satellite imageries have been interpreted using the different techniques of digital image processing such as supervised classification, and post classification etc. The maximum likelihood classification scheme, based on the field visit by various latitude and longitude coordinates and the photographs of the different features using GCP (Ground Control Positioning) receiver was used. The impacts of change have been studied using change detection technique. The change study notified the different variations in the land cover and the land use set up. It is believed that this type of study in connection of occurred change due to the natural disaster in region can be very useful for developing the landslide risk, hazard and the vulnerability models which would be benefited for the decision makers in future to redevelop the regions.
