Urban Underground Pipeline Geographic Information Systems Design And Development

The underground pipelines information is an important part of the city digitization, as well as the most basic material foundation of the construction of the city information. With the rapid economic development, urban development is changing, the dependence of underground pipelines and other infrastructure is becoming stronger and stronger. Therefore, the establishment of urban underground pipeline information system has a certain necessity and practical significance.In this paper, the urban underground pipeline geographic information system is the main object of study, and based on urban underground pipeline in the business of research and needs analysis, the functional structure of information systems, database storage model and component-based development of GIS technology was depth researched. The main contents include:1.Detailed study of the urban underground pipeline information systems requirements and business situation, using the UML analysis and designing tools to build a information system model of requirement.2.Based on results in the needs demands, using object-oriented technology to design urban underground pipeline GIS capabilities framework, and a storage model structure integrating spatial data and attribute data.3.Summarized the key technology line of system development, practice implementing the main functions of urban underground pipeline GIS using components of TatukGIS.
