The Research And Realization On Underground Pipeline Management Information System

The thesis introduced the underground pipeline of my country and the necessary for enhance management of underground pipeline information, includes the exploitation manner of system, the choose of GIS flat roof, the design of system database, the collection of map data and attribute data, in the last the exploitation and realization of system have been particularly introduced.The thesis discussed that how to construct and achieve the information management system of underground pipeline's map. We design a system of underground pipeline for CAD in the thesis, we design underground pipeline's database structure and solve three problems: graph and attribute's management, underground pipeline's seam, drawing section.Now, the theory has been used and checked by the user in shandong qingdao city. Functions can completely sufficed the daily management of underground pipeline.
