摘要:

目前,我国已建立多种基础空间数据库,但现有空间数据库管理系统中,地图制作、标准地图管理等仍需要采用标准分幅来满足统一管理的需要。如何更有效地管理海量分幅空间数据,并实现对其快速检索成了多尺度基础空间数据库建设亟需解决的问题之一。本文分析了电子接图表,实现了空间数据接图表的可视化,集成了现有的空间数据库管理与数据库可视化操作的功能;依据空间数据不同的比例尺类型、要素类型、几何类型,自动计算标准分幅编号、绘制分幅边界;提供空间数据库海量数据检索技术方法与参数传递方案、基于数据存储的逻辑结构设计数据检索方案,并总结出空间数据优化存储策略与高效管理方法。应用案例表明,空间数据库电子接图表能够提高分幅空间数据的可视化管理与检索效率,对涉及大规模空间数据库可视化管理和检索应用需求,有很好的理论和实际应用价值。

Abstract:

At present, all kinds of large-scale spatial databases have been developed in China, which adopt the international standard of map dividing method and coding scheme. Compared with the common database, the volume of spatial database are massive in terms of spatial location, which heavily hinder the efficiency and effectiveness of data processing. Thus, how to manage massive spatial data effectively and efficiently has been the problem urgently to be solved. In recent years, with the rapid development of geographic information system (GIS) technology, spatial database management efficiency is greatly improved, which has become an important tool for spatial database management, analysis, acquisition, processing, storage, updating and maintenance. In order to satisfy the need of production and management of spatial data, this paper discuss a method of map dividing of spatial database, functions of common spatial database management and processing operation are integrated in the spatial database map dividing tools. The main functions of the spatial database map dividing tool are to visualize the storage status of spatial data, representing topological relationships, projection, spatial reference, various map scale, feature type and geometry type, as well as automatically drawing the border of standard map according to different scale. In addition, the extra information of the spatial data could be retrieved and displayed by feature type, geometric type of spatial data, which traditional method of map dividing could not achieving. Furthermore, based on the design of the logical structure of data storage, and to realize the optimization strategy of spatial data storage and retrieval, this method provided massive date retrieval technique and parameterized scheme for spatial database management, the application of map dividing in Management System for spatial database of Shanxi province shows that it provides an effective and efficient method of the manipulation and management of spatial database.
