基于ArcGIS平台的厂区地下管网空间分析

针对大型厂区地下管网规模庞大复杂且难以管理的问题,采用了一种基于ArcGIS平台的C/S+B/S混合开发模式。把传统地理信息系统客户端管网空间分析功能提至服务器端处理,在B/S端采用碰撞检测算法对管网进行碰撞分析,同时采用高效的线性内插法计算断面分析中所需的交点高程数据。系统上线运行结果表明,该系统能够更好地对原本不可见的地下管网进行有效的空间分析,从而实现对厂区地下管网的数字化管理。

Underground pipe network spatial analysis in large plant with ArcGIS

To resolve the problem that underground pipe network of plant is large,complex and difficult to manage,the C/S+B/S mixed development model based on the ArcGIS platform was used.This paper aimed to transfer the spatial analysis of the traditional Geographic Information System(GIS) from C/S to B/S.Collision detection algorithm and efficient linear interpolation method were used in B/S client,and moreover an optimized relational database management model was proposed.The system running results show that the system could make spatial analysis of the invisible underground pipe network better and more effective,and achieve the digital management of underground pipe network in large plant.
