| Pipeline is the lifeblood of a city is a city indispensable auxiliaryfacilities, with the city's development and construction, pipeline showing avariety increased, complex structures, from the ground to go undergroundtrends, the management of this pipeline to bring a lot of inconvenience. Thetraditional manual approach to the paper maps storage map information to theforms, records of text and data, which makes day-to-day management of theinformation pipeline abnormal cumbersome. To find information on aparticular region often require costly pipeline staff a lot of time. In addition,under certain environmental pipeline system is not suitable for manualmanagement, such as industrial chemical enterprise network is often built in apolluted environme nt, which will certainly need a means to mock this kind ofenvironment, to ensure that it is production services. Many examples of thedata or to seek a new pipeline information management approach nowextremely urgent.With the development of computer technology, especially geographicinformation systems technology, information management to the pipeline witha new way of thinking and method, in essence, is a technology revolution.GIS study for the geographical entity, a geographic entity based on the spatialrelationship between them establish the link, then proceed to informationmanagement, decision support and so on. Therefore, the GIS scope of thestudy is very extensive, as long as it is in the level of human cognition, in acertain way to express things or objects can be used geographic informationsystems to be studied. This paper through geographic information system tocreate a complete set of information management systems pipeline, throughindividual or collective learn from other successful experiences, we hope todevelop a pipeline from the bottom to support the basis of twodimensionaldata model geographic information system platform, in this pipeline on thebasis of the relevant functional information management , including computerdata pipeline storage, management, retrieval, analysis, and support for daytodaywork of policymaking.Pipeline is the lifeblood of a city is a city indispensable auxiliaryfacilities, with the city's development and construction, pipeline showing avariety increased, complex structures, from the ground to go undergroundtrends, the management of this pipeline to bring a lot of inconvenience.

Many examples of thedata or to seek a new pipeline information management approach nowextremely urgent.We are in the development pipeline Information Management System(PIMS), the two-dimensional GIS MapBase basic platform is the mostimportant part of it involves computer graphics, computer data structure andother theories. PIMS was mainly the function of topology and networkanalysis from their theoretical support, such as Dijkstra shortest pathalgorithm, Prim minimum spanning tree algorithm. PIMS also draws on thedevelopment of individual or collective other's successful experience,particularly in the data structure and algorithm optimization get a lot ofinspiration, such as the quadtree and octree spatial indexing algorithm isimproved through other be successful.This paper Pipeline Information Management System Design andDevelopment of a systematic analysis and research, concrete embodiment ofthe following:(1) on the status of pipeline information management conducted an indepthstudy, the presence of which explored issues of these issues is based onthe integrated response of GIS information management system buildingpipelines need. In light of its own characteristics, we also explored thefeasibility of the development of PIMS.(2) In accordance with the characteristics of geographic informationproject, we studied the Pipeline Information System software engineeringmodel construction, and put forward their detailed development plan.According to the actual work of the pipeline information management needs,we designed a pipeline information management system structure, includingsoftware function modules structure, composition, data processes, networkarchitecture, and so on. These are building a project or project basis, they canguide the works or construction projects normal in an orderly manner.(3) from the ground on a two-dimensional GIS platform based theoriesand methods were studied, including geographic information system data structure, computer graphics algorithms, data storage and retrieval, databasetheory, space and search. Concerning the analysis of the pipeline networkanalysis algorithm was studied and a concrete realization.(4) information management system for 3D pipeline was practicalresearch, starting from the actual application will be three-dimensionalGIS and pipeline information management, the breakthrough 3DGIS purely visualeffects, and the actual connection, the three-dimensional data model andpipeline analysis model was studied.Pipeline is the lifeblood of a city is a city indispensable auxiliaryfacilities, with the city's development and construction, pipeline showing avariety increased, complex structures, from the ground to go undergroundtrends, the management of this pipeline to bring a lot of inconvenience.
