摘要
随着城市矢量空间数据类型不断增多、更新速度不断加快,传统的基于分幅或非标准格网分区的管理模式较难形成高效的数据综合应用体系,本文通过建立多层级、多专题的城市矢量空间数据库,引入多级空间数据库的同步机制,使用要素级的增量更新策略,实现了城市矢量空间数据的要素级管理和多时态特性,建立起了高效的数据生产与数据应用的一体化作业体系。
As the types of urban vector space data continue to increase and the update speed continues to increase,traditional framing or non-standard grid partition management is difficult to form an efficient data comprehensive application system.In this paper,by establishing a multi-level and multi-topic urban vector spatial database,a synchronization mechanism for multi-level spatial databases was established.Using the feature-level incremental update strategy,the feature-level management and multi-temporal characteristics of urban vector spatial data were realized with high efficiency.An integrated operating system for data production and data application has been established.
