内河航运工程GIS平台建设技术与应用

Technology and application of GIS platform construction for inland water transportation engineering

京杭运河黄河以北复航工程涉及山东、河北、天津、北京4个省市,线路长度800 km,建设周期5~10 a。项目研究过程中存在资料庞杂、规划方案变更及参建各方人员变动等情况,传统的设计与管理软件难以实现多源数据的融合及各阶段数据的有效利用。介绍了一种基于三维GIS技术解决上述问题的方法及其应用场景,该内河航运工程规划设计软件平台将模型数据、影像数据、矢量数据、属性数据和设计文件进行集成,实现规划设计一体化地理大数据管理,实现信息的快速查询与统计分析、数据的共享等。对平台建设过程中的技术及规划阶段设计者关注的功能点进行阐述,为GIS技术在水运行业应用提供可借鉴的方法与思路。

The resumption project of the Beijing-HangzhoUGrand Canal to the north of the Yellow River,involves Shandong,Hebei,Tianjin and Beijing,with a length of 800 km and a construction period of 5~10 a.In the process of project research,there are complicated data,planning scheme changes and personnel changes of all parties involved in the construction,etc.,so it is difficult for traditional design and management software to achieve the integration of multi-source data and the effective use of data at various stages.The paper introduces a method and its application scenarios to solve the above problems based on 3D GIS technology.The planning and design software platform of inland waterway project integrates model data,image data,vector data,attribute data and design files to realize management integration of geographic big data in planning and design stage,realizes the rapid query and statistical analysis of information,data sharing,etc.This paper expounds the technologies in the process of platform construction and functions that designers pay attention to in the planning stage to provide reference methods and thoughts for the application of GIS technology in the water transportation industry.
