Research on Geographic Information System of Underground Pipe Network of Dalian University

With the rapid development of campus construction, the corresponding water supply and drainage, heating, electricity and other facilities are also synchronized expansion, update. In order to realize the information management of underground integrated pipe network efficiently, we propose and develop GIS technology based on Auto CAD and geographic coordinates and attribute coordinates, and realize the digital management and analysis of underground pipe network data of campus. The query, the statistical output and the real-time renewal and so on, has completed the geographic data and the attribute data and the Auto CAD gallery linkage, the line has become the visualization geographic information system, achieved the school underground pipe network information modernized management level.
