Development of a Performance Evaluation System Based on Baidu Map Fixed-point Observation Data

The results1 of traditional seismic monitoring data evaluation are mostly based on text description and graph display. Earthquake researchers still need to spend a lot of time on analysis, and it is difficult to correlate the results with the time of the earthquake, the epicenter, and the array. The time, location and magnitude of an earthquake are often referred to as the three elements of an earthquake in seismology. The goal of the system is to realize the multi-dimensional data visualization of seismic monitoring, and to closely correlate the evaluation results with the three elements of the earthquake, so that the earthquake workers can further study and analyze the seismic evaluation data. Therefore, this paper needs to design a software system to graphically display the results of the seismic data evaluation. This article mainly uses Baidu map JavaScript API secondary development technology to display Baidu map on the Webpage, realize the evaluation results on the map to display and compare the map; use ECharts chart to draw plug-ins and other techniques, draw the evaluation results on the map. The graphs are displayed and compared. The ellipse long and short axis intensity algorithm is used to simulate the elliptical seismic intensity map, and the impact of the earthquake on the surrounding building stations is analyzed by simulating the earthquake. Through the above key technologies, the seismic data is transformed into GIS spatial data efficiently. The correlation between the map and the three elements of the earthquake is provided to provide technical support for the earthquake workers.
