Abstract:Earthquake sites are different from general disaster sites, and their disaster areas are relatively large. However, collected disaster information based on remote sensing can prove scattered and confused, and cannot form visual analysis results. To solve this problem, a disaster information collection system for a large earthquake area, based on visualization remote sensing technology, was designed in this paper. The system hardware consisted of a network communication layer, a data collection layer, a database layer, a GIS remote sensing platform layer, and an application layer. The advantages of using remote sensing to gather information was harnessed, and the three-dimensional reconstruction technology of GIS was applied to visualize the disaster information. The experimental results showed that the maximum response time of the system is 1.857 s, and the maximum CPU occupancy and consumption were 80.8% and 1 656 MB, respectively. There was a high degree of recurrence of information visualization.
