【摘要】 铁路信息化和数据标准化对铁路用地信息管理提出了更高的要求,多源空间信息集成技术是集成各种铁路空间数据、实现铁路用地信息化管理的基础。本文根据铁路用地空间数据的来源和组成,针对数据的多源、多尺度、动态等特点,提出了基于元数据驱动的铁路用地空间数据集成技术框架,设计了三层分布式C/S铁路用地信息系统结构,所构建的"武汉铁路局铁路用地综合信息管理系统"已取得理想的实际应用效果。更多还原

【Abstract】 Railway information and data standardization of railway land have brought forward higher requirements for information management. Multi-source spatial information integration technology is the foundation to integrate various spatial data and realize information management of railway land. According to the sources and composition of railway land spatial data, and the characteristics of multi-source data, multi-scale and dynamic change, this paper presents a data integration framework based on the meta-data driven technology and designs a three-layer distributed C/S system structure. The "Wuhan Railway Bureau railway land integrated information management system" has already made good practical application.更多还原
