Abstract:When GIS technology is used to evaluate the seismic hazard level, because of the poor rationality of its terrain control points, the accuracy of the collected remote sensing images is low, and the seismic rating is not sufficiently exact. A new electronic emergency assessment method for remote sensing information hazard levels of earthquake disasters is proposed in this paper. The method of geometric image correction is used to segment the image of the remote sensing, and the surface control points are chosen based on the cutting result. The useful information on remote sensing is extracted, and evaluation indexes for remote sensing interpretation are established. The information of each evaluation unit is ranked and divided, then the online emergency assessment of remote sensing information hazard level is completed. The effectiveness of the proposed method and the GIS seismic hazard rating method were compared in a simulation experiment. The experimental results show that the proposed method will increase the selection rationality of control points for the disaster terrain, make the acquired remote sensing images clearer and the results of the disaster rating more precise.
