摘　　要：研究目的:针对铁路测绘数据具有呈带状、分带多以及数据格式、存储位置均异构等特点,且数据量庞大、数据在各专业之间的流转效率低、数据管理不规范、数据重复使用效率低下等问题,本文进行基于元数据的测绘数据集成共享关键技术探讨,为铁路行业测绘数据成果规范管理、提高成果流转效率和服务手段等提供借鉴。研究结论:本文针对铁路测绘数据入库和查询等问题,提出了基于元数据的测绘数据集成共享方法,建立了铁路测绘元数据标准以及实现了基于接图表的三维可视化查询技术,为铁路测绘数据管理和应用提供了强有力的工具。研究结果表明,该方法完全满足铁路测绘数据规范管理和高效应用的需求。Research purposes： Aiming at the railway mapping data＇s characteristics of the zonal shape, multi- format and multi - location with huge data size and the problems of the low efficiency of data exchange among various professional areas, abnormal management of data and low efficiency of data re - usage, this paper discusses the key technology for the integration and sharing of metadata - based mapping data for providing the reference to the normal management of the railway mapping data and improvement of the exchange efficiency and service quality. Research conclusions：For solving the problems mentioned above, a method is offered for integration and sharing of the metadat -based mapping data, the standard is worked out for the railway mapping metadata and the connection chart - based three -dimensional visualization inquiry technology is developed for providing the powerful means for the management and application of the railway mapping data. The research result shows this method can meet the demands of the normal management and high - efficient application of the railway mapping data.
