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 research has notable features of multi-source heterogeneity. The data of the results generated during the analysis and research also show diversified characteristics. With the secondary development platform of MapGIS K9 geographic information system, a multi-source heterogeneous remote sensing image database system for seismic research based on file storage is designed and implemented. The seismic multi-source heterogeneous remote sensing image database system can effectively store and manage auxiliary data such as image data, vector data and document data. According to the characteristics of remote sensing images used in seismic industry, the data browsing, data catalog and operation designed and implemented, the data retrieval As well as data security and user rights functions to meet the operational needs of users in seismic research. The database system has achieved good results in the application and storage of remote sensing images in the high score demonstration area.
