基于ArcScene平台的三维管网系统的研究

Research on 3D Pipe Network System Based on ArcScene

目前二维管网系统较为成熟,但二维管网系统对于重叠的管网数据的表达有限,同样也无法真实地展示出管网的管径、材质信息与管点设备类型等信息。而三维管网技术发展较慢,成熟的系统并不多。大多三维管网系统缺乏地形数据,管网立体的空间效果较差。重点分析了二维管网数据和三维管网数据的相关性,三维管网数据与地形栅格数据之间高程的关系,设计了分层的三维空间数据库。通过ArcScene平台进行了数据整合和系统的实现,实现了二、三维管网数据以及地形栅格数据之间的无缝结合,实现了基础浏览、定位查询以及多种管网分析功能。系统整体空间性强,真实反映出管网的空间关系,且功能齐全。

The two-dimensional pipe network system is more mature but has limited expression for the overlapping pipe network data,and also cannot really display the information of pipe diameter,material information and pipe type equipment.The development of three-dimensional pipe network technology is slow,and mature systems are few.Most of the three dimensional pipe network systems lack terrain data,and the spatial effect of the pipe network is poor.In this paper,we emphatically analyze the correlation between two dimensional pipe network data and three dimensional pipe network data and the relationship between 3D pipe network data and terrain grid data.After that we design the layered three dimensional spatial databases.The data integration and realization of the system are carried out through ArcScene platform.The system realizes the seamless integration of two and three dimensional pipe network data and topographic grid data,as well as basic browsing,positioning query and several pipe network analysis.The whole system has strong space and truly reflects the spatial relationship of the pipe network with complete functions.
