| The Three-Dimensional Simulation System is widely used gradually in the context of the technology of computerized and informatization are changing rapidly.It’s not only be applied to the planning and management of the city,but also plays an important role in the assistant decision-making of the city.This article revolves around the data structure and standards that arise in the construction of Three-Dimensional city,and talks about the formulation and application of Three-Dimensional City Model based on the three-dimensional digital city construction and practical applicationFirst of all,the article analyzes and explores surrounding the goal to study,analyzes and summarizes the spatial data of underground and surface space of the city;then start to design the structure centered on Software and Hardware system,city data model,system function and so on.Furthermore,the article also discusses the visualization model which exists in modern society,and made a further explanation about city terrain data structure,thereby expounding on the model used in this article.Finally,the article summarizes the technical points in the city modeling,and built on a practical example so the techniques and ideas that have been studied have been certified.The article through studies confirm that construct the City Three-Dimensional Simulation System is conducive to carry out the work in other aspects of the city.Such as tourism publicity,town planning and intelligent traffic,etc.,and also can serve the modern information society better. |
