基于Python的地震影响场自动生成与发布技术的研究与实现——以陕西省为例

Research and Implementation of Automatic Generation and Release for Seismic Influence Field Based on Python–Take an Example of Shaanxi Province

基于陕西省不同分区的椭圆和线源2种烈度衰减模型,采用Python自动化技术和Arcpy空间绘制技术自动生成地震影响场方法,通过ArcGIS Server实现影响场地图服务的自动发布。系统无需人工干预,提高了产出效率,提供标准网络地图服务接口,方便地震影响场的调用;同时建立客户端实现对地震影响场进行查询、管理和手动修正等功能,增加系统的实用性;最后通过测试数据,对系统产出和发布的效果进行验证。

On the basis of the research of automatic response technique by Python language and Arcpy space rendering technique,and the building of ArcGIS Server map service site,this thesis realizes the automatic Generation and release of the seismic influence field data of the two kinds of intensity attenuation models based on the different partitions in Shaanxi province.The system requires no manual operation and provide standard network Map Server interface for other systems to facilitate data sharing.At the same time,a client-side is established to realize the function of query,management and manual correction of the seismic impact field,so as to increase the practicability of the system.Finally,the effect of system rapid output and release are verified by the test data.
