基于可视化遥感的地震大区域灾情收集系统

地震现场与一般灾害现场不同，其受灾区域较大，常规的基于遥感信息进行灾情收集时，采集信息零散混乱无法形成可视化直观分析结果。为解决该问题，设计基于可视化遥感技术的地震大区域灾情收集系统，利用遥感信息采集大区域的优势，配合设计网络通信层、数据收集层、数据库层、GIS遥感平台层和应用层组成的系统硬件，采用GIS三维重构技术，对灾情进行可视化呈现。实验结果说明，系统最长响应时间为1.857 s，最大CPU占用率和消耗分别是80.8%和1 656 MB，信息可视化重现程度高。

A Disaster Information Collection System Based on VisualizationRemote Sensing Technology in Earthquake Areas

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.
