基于GIS技术的地震档案查询系统

Temporal and Spatial Correlation Between Seismic Monitoring Events and Archives Based on GIS

针对中心的各类地震观测档案资料建立了一个地震档案数据库,基于观测档案的地理属性在GIS平台上建立相应的时空数据库,建立档案数据库与空间数据库之间的关联关系,使空间数据与档案数据可以互相查询,实现以地理定位为基础的信息与其对应的档案数据的准确、快速双向检索,建立了一个基于GIS技术的地震档案查询系统。

According to all kinds of seismic data in the center, a database of seismic archives was established. The COl;responding spatial-temporal database on the GIS platform was also established based on the geographic attributes of the observation files. Then the association relationship between the archive database and the spatial database was built, so the spatial data and the file data can query each other, realizing the accurate and fast two-way search of the information based on the geographic location and the corresponding file data. A query system of seismic files based on GIS technology was established.
