基于Python的地震应急专题图快速出图技术研究

Research on rapid mapping technology of seismic emergency thematic map of Henan Province based on Python

利用Python语言编写了地震应急专题图快速产出的脚本程序,当地震发生后,由地震应急值班人员启动该脚本程序,该系统能够自动获取地震灾情评估系统产出的地震三要素、地震影响场、震中距等,并调用预制的地震应急指挥专题图模板,能够在震后5分钟内实现地震专题地图的快速产出,有效地解决了地震制图难、效率慢、质量不高的问题,能够为地震应急救援提供有力的技术支持。

In this paper,we write a program script for rapid generation of earthquake emergency thematic maps using Python language.When an earthquake occurs,the personnel on duty will trigger the program.The system can automatically acquire the three elements of earthquake,earthquake influence field and epicenter distance produced by the earthquake disaster assessment system.Then the program will use the template of earthquake emergency thematic maps.The rapid production of earthquake thematic maps can be realized within 5 minutes after the earthquake.This program effectively solves the problems of difficulty,low efficiency and quality of seismic mapping,and can provide strong technical support for earthquake emergency rescue.
