| Abstract: | The application of an integrated technology of remote sensing and geographical information system in monitoring and evaluating of dust storm disasters is discussed, and an identical mathematical model for dust storm monitoring using remote sensing technology is obtained, it explains that the operational system used in dust storm disaster evaluation using GIS technology. Based on the overlay analysis of the dust storm information and the ground information, the system can assess the dust storm disaster rapidly and exactly. |
