摘要
土地空间信息往往涉及大量的报表、文字、图形资料等,信息类型多样,给信息利用和查询带来了很大的难度。为了提升信息查询质量与效率,文中设计基于GIS技术的土地空间信息查询系统。借助B/S三层架构设计三层系统框架,包括数据库层、土地空间信息管理层以及可视化层;利用GIS中的MapInfo工具建立空间数据库,并建立属性数据库;以GIS技术为基础,设计系统功能模块,主要包括土地空间信息集成模块、土地空间信息管理模块、土地空间信息查询模块,由此实现信息查询系统设计。实验结果表明:所设计系统的F_(1)⁃Measure值更高、查询时间更短,由此证明该系统的查询结果准确、全面,查询速度较快。
Land spatial information often involves a large number of reports,text,graphic data and other information types,which brings great difficulties to the utilization and query of information.Therefore,a land spatial information query system based on GIS technology is designed to improve the query quality and efficiency.With the help of B/S three⁃layer architecture,a three⁃layer system framework is designed,including database layer,land spatial information management layer and visualization layer.The MapInfo tool in GIS is used to establish spatial database,based on which the attribute database is established.On the basis of GIS technology,the system function module,which mainly includes land spatial information integration module,land spatial information management module and land spatial information query module,is designed.So far,the design of information query system is realized.The experimental results show that the value of F_(1)⁃Measure of the designed system is higher and its query time is shorter,which proves that its query results are accurate and comprehensive,and its query speed is faster.
