Design And Realization Of Urban Sewage Pipe Network Geographic Information System Based On ArcEngine

As cities in our country develop rapidly, the urban sewage pipe network begin to expand rapidly and reconstruct in large scale, which requires better operation and management. However, manual management is adopted currently in most of the cities in China to manage information of city sewage pipe network, and it has obvious disadvantages. And GIS (Geographical Information System) has superior functions of data processing, analyzing and managing, and it is an effective technology to improve management of city sewage pipe network.Urban sewage pipe network GIS is a new technology integrating computer graphics and data to store and process spatial information. It combines attribute information and spatial information of facilities related to sewage pipe network, then display and output to the user the accurate and visual information in form of images and texts according to user's necessity, therefore, to meet requirements of municipal departments on operation and information inquiry of sewage system.Based on necessity of daily management of sewage pipe network and functional characteristics of GIS, this thesis studies on mainly the analysis and design of urban sewage pipe network GIS, does demand analysis of urban sewage pipe network GIS and comes up with functions meeting demands and design principle, finally brings forward development method which should be adopted for the system. Thus, this thesis studies objects to be managed by the system, classification, organization and management of data, proposing plan of data by organized by layers and codes. And then design the functions of the system to meet actual demands.Urban city sewage pipe network GIS which takes sewage pipe network of Yuanyang County as basic data is established in C#.Net environment using component GIS software -ArcEngine. It has functions of data format converting, graphics managing, data inquiring and analyzing, and assisting computation. And this thesis discusses the design and realizing way of city sewage pipe network GIS.
