Structuring method for three-dimensional visualizing system of urban synthesis pipeline network

The invention relates to a structuring method for a three-dimensional visualizing system of an urban synthesis pipeline network. The method comprises the following steps: establishing a central database for the urban synthesis pipeline network; establishing a two-dimensional texture database; setting a spatial data engine; reading and modeling to the central database and the texture database through the spatial data engine to construct overground and underground two-dimensional views and a three-dimensional visualization scene; and establishing a corresponding relation between two and three dimensional data planes and visual planes, wherein the data planes correspond to and the geographic coordinates of the two-dimensional view and the three-dimensional scene of the system, the visual planes correspond to various spacial geographical object models in the three-dimensional scene and map symbols of the two-dimensional view, the purpose of two-dimensional and three-dimensional linkage isachieved, the function which is not easy to realize in the three-dimensional scene or the macroscopic function is realized through the two-dimensional view, the function which cannot be realized in the two-dimensional view or the function which is less real is realized through the three-dimensional scene, so that the purpose of complementing each other is achieved, and the effective management ofthe urban synthesis pipeline network is further realized.
