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。
Railway informationization and data standardization put forward higher requirements for railway land use information management. Multi-source spatial information integration technology is the basis for integrating various railway spatial data and realizing railway information management. According to the origin and composition of spatial data of railway land use, according to the multi-source, multi-scale and dynamic characteristics of the data, a framework of spatial data integration for railway land based on metadata driven is proposed. Three layers of distributed C / S railroad land Information system structure, built by the “Wuhan Railway Bureau railway integrated information management system ” has achieved the ideal effect of practical application.
