地震多源异构遥感影像数据库系统设计与实现

Design and realization of Multi-source heterogeneous Earthquake Remote Sensing Image Database for Earthquake research

应用于地震研究中的遥感影像数据具有多源异构的显著特点,分析研究过程中产生的成果数据亦呈现多样化的特性。借助MapGIS K9地理信息系统二次开发平台,设计并实现了基于文件方式存储的应用于地震研究中的多源异构遥感影像数据库系统。地震多源异构遥感影像数据库系统能够有效地存储和管理影像数据以及矢量数据、文档数据等辅助数据,针对地震行业遥感影像的使用特点,设计并实现的数据浏览、数据目录及操作、数据检索以及数据安全与用户权限功能,能够满足地震研究中用户的操作需求。数据库系统在高分示范区遥感影像存储与共享应用中取得了良好的效果。

The remote sensing image data used in earthquake researchare multi-sourced and heterogeneous,and the outcomes of the analysis and research process are different from each other for different application.In this paper,based on the MapGIS K9 GIS software platform,we design and implement an earthquake remote sensing image database system based on file storage mode.Earthquake remote sensing image database system can effectively store and managethe image data and their auxiliary data like vector data and document data which are used along with the remote sensing data in earthquake research,even the daily monitor and response of earthquake.Based on the database,we designed and developed a convenient management system providing data browsing,data directory and operation,and data retrieval functions to meet the actual demand of earthquake researchers.The database system has achieved good effect in the application of remote sensing image storage and sharing in the demonstration area.
