A research on data integration and application technology of urban comprehensive pipe gallery based on three‐dimensional geographic information system platform

Three-dimensional Geographic Information System (3D GIS) technology is often used in geology, mining, hydrology and other fields. It also intelligent management of urban comprehensive pipe gallery projects, because the real environment with sky, ground, underground can be intuitively simulated virtual reality by 3D GIS platform. Through research on data integration application gallery, model project created based Building Modelling technologies, a pipelines network information system has been developed to realise various data, including model, 2D or ground etc. On this basis, functions planning approval management, safety analysis disaster prevention decision-making projects further realised. The results have applied construction process sub-centre Beijing.
