摘要
将地理信息系统(GIS)与公路路网管理系统相互集成,可借助地理信息系统强大的空间数据分析处理能力和数据可视化分析能力,激活公路路网数据潜能,使繁杂抽象的数据变得具体易懂,对于交通运输数据管理工作具有非常重要的现实意义。通过分析路网数据的现状,提出地理信息系统与公路路网管理系统相互集成要解决的关键技术问题为属性数据和空间数据的融合,包括参照系融合和存储方式融合。并有针对性地提出了解决方法,通过建立线性参照系统的方法实现属性数据桩号参照系与空间数据大地参照系的融合;通过在应用层和数据层中间建立数据接口层,将数据存储方式和底层的数据结构与业务应用相互分离的方法打通数据壁垒,实现数据存储方式融合。系统已经应用到山西省运城市路网计划数据管理工作中,取得到了很好的应用反馈。
The geographic information system(GIS) has powerful ability of spatial data analysis and data visualization, so the geographic information system integrated with the existing road network management system, can activate the highway road network data potential, make it specific to understand complex abstract data, for the transportation management has very important practical significance. By analyzing the current situation of road network data, proposes that the key technical problem to be solved in the integration of geographic information system and highway network management system is the fusion of attribute data and spatial data, including the fusion of reference system and the fusion of storage method. The solutions are proposed, the combination of the roadway stake number reference system of the attribute data and the ground reference system of the spatial data is realized by establishing a linear reference system, by establishing the data interface layer between the application layer and the data layer, the data storage mode and the underlying data structure are separated from the business application to realize the fusion of data storage mode. The system has been applied to the management of highway network planning data in Yuncheng city, Shanxi Province, and good application feedback has been obtained.
