摘要
为了解决在震后初期地震应急专题图在生产中所面临着的专题内容多、幅面种类多、时间十分紧迫等问题。在地震应急专题图自动化生产系统的基础上,充分挖掘和利用服务器的CPU等物理资源,进而利用ArcPy进行了多进程生产模式的设计开发。经实验对比,生产具有相同分辨率和幅面数量的专题图,相较传统模式而言,多进程模式将生产时间由原先的1308秒缩减至377秒,效能提升约347%。在实际应用中,脚本化的程序即拷即用,让功能部署变得更加简单便捷。应急专题图的标准化、产品化、生产效能均得大幅提升,地震应急信息化服务水平得到显著进步。
In order to solve the problems of the earthquake emergency thematic map within so many topics, kinds and urgent time in the early post-earthquake period. On the basis of automatic production system of earthquake emergency thematic map, the multiprocess production mode is designed and developed by using ArcPy, which makes full use of physical resources such as CPU of server. Compared with the traditional mode, the multiprocess mode reduces the production time from 1308 seconds to 377 seconds and improves the efficiency by about 347 %. In practical applications, scripts are used to make function deployment easier and more convenient. The standardization, production and production efficiency of emergency thematic maps have been greatly improved, and the level of earthquake emergency information service has been significantly improved.
