基于“天地图”的地震专题图自动出图技术研究与实现——以陕西省为例
发布时间:2018-09-01 20:15
【摘要】:结合地震应急中对专题图产出的要求,研究"天地图-陕西"的切片方式和服务方式,在Arc GIS中实现了天地图瓦片数据与矢量数据相结合。通过研究数据库监听技术、基于Python语言和Arc Py包的出图技术,实现地震三要素的自动获取和影响场产出,并最终实现了基于天地图数据的地震专题图自动产出,完全无需人工操作,提高了专题图出图效率。
[Abstract]:According to the demand of special topic map output in earthquake emergency response, the slicing mode and service mode of "Tianming-Shaanxi" are studied, and the combination of tip-tile data and vector data is realized in Arc GIS. Through the research of database monitoring technology, based on Python language and Arc Py package mapping technology, the automatic acquisition of seismic three elements and the impact field output are realized. Finally, the automatic output of seismic thematic map based on sky map data is realized. No manual operation is required, and the efficiency of thematic mapping is improved.
