The Application of Remote Sensing Technique on the Disaster Risk Assessment

In the past 40 years, remote sensing technology was widely used for hazard warning and monitoring evaluation study because of its advantages of a wide range of observation, a large amount of information, fast access to message, and strong comparability. By analyzing of using remote sensing technology in the aspects of natural disaster risk assessment, land use trends monitoring, greenhouse gas emissions survey in this paper, it can be considered that the research of disaster risk assessment system based on remote sensing can enrich the theories and methods of disaster risk and vulnerability assessment.
