Assistant Design System of Urban Underground Pipeline Based on 3D Virtual City

Abstractwith the expansion and utilization of underground space resource in cities, the intensity and density of urban underground pipelines are dramatically increasing. How to efficiently utilize the up-to-date technology and realize underground space resources’ management, visualization, assistant design and mine applications, are hot issues in the current virtual city development. In this paper, we present a framework for Urban Underground Pipeline Assistant Design System (UUPADS) based on 3D virtual city by secondary development. UUPADS is designed for organizing and managing the information of underground pipeline efficiently. It includes the functions such as 3D virtual city platform building, 3D pipeline dynamic visualization, pipeline editing and assistant analysis, etc. The land-ground data, such as remote sensing image, Digital Elevation Models (DEM), roads and 3D house, etc. are integrated and managed by 3D virtual city platform. The underground 3D pipeline visualization is implemented with the location reference to the land-ground data and assistant analysis is realized. Taken one region of Jilin province as research data, UUPADS is feasible in conducting 3D pipeline interactive management more efficiency and convenience
