【摘要】：国土规划是空间规划体系中层级最高的规划,是国土资源开发利用与整治保护相关规划编制的重要基础。要做好相关规划,需要对规划区内自然、经济、社会等数据集进行灵活有效的利用和组合。针对国土规划编制中对多源异构空间、非空间数据集成和抽取特定数据的迫切需求,提出了一种基于虚拟数据库的国土规划多源异构数据集成方法,利用虚拟数据库实现分布式数据源的虚拟组织与透明访问,用GML实现多源异构数据格式的标准化,并开发了国土规划信息共享原型系统,在此基础上进行了实践使用。从现有数据库中抽取相应的数据集和数据项,构建全局虚拟数据库,由于虚拟数据库并不改变现有数据库的应用系统工作模式,保证了原始数据更新的有效性,以及数据的完整性。
[Abstract]:Land planning is the highest level planning in the spatial planning system, and it is an important foundation for the development and utilization of land and resources and the compilation of relevant planning for regulation and protection. In order to make good planning, it is necessary to make flexible and effective use and combination of natural, economic, social and other data sets in the planning area. In order to meet the urgent need of multi-source heterogeneous space, non-spatial data integration and data extraction in land planning, a method of land planning multi-source heterogeneous data integration based on virtual database is proposed. The virtual organization and transparent access of distributed data source are realized by using virtual database, the standardization of multi-source and heterogeneous data format is realized by GML, and a prototype system of land planning information sharing is developed, which is used in practice. The corresponding data sets and data items are extracted from the existing database, and the global virtual database is constructed. Because the virtual database does not change the working mode of the existing database application system, it ensures the validity of the original data updating. And the integrity of the data.
