摘要
地理信息具有空间分布特性和时态特性,地理信息数据的快速更新已成为目前研究热点。本文首先通过建立大庆高新技术开发区基础地理信息时空数据库管理系统的应用实例,从数据的收集、组织与处理、数据库建立等过程进行详细的阐述,并实现了数据库的动态关联与更新、时空回溯以及动态可视化等。最后通过对系统功能模块的应用分析,提出对系统软件测试的测评建议。该应用数据库管理系统的建立,为基础地理信息动态数据库的建设提供一个比较完整的解决方案,也为今后的应用推广提供必要的技术支持和基础保障。
Based on the characteristics of spatial and temporal distribution,the rapid update of geographical information data has become a research hotspot.The Hi-tech Development Zone of Daqing city was taken as example to study the application about the temporal and spatial database management.The data acquisition,organization and processing,and database construction was detailedly elaborated,and the function of dynamic association and update,temporal and spatial retrieve,and dynamic visualization of database was achieved.Finally,through the application of the system function analysis,the evaluation of the system software testing was obtained.According to the establishment of the database management system,the complete solution was provided from the dynamic geospatial fundamental database,which provided the necessary support and infrastructure protection in future.
