Realization method of three-dimensional real scene of infrastructure in Tian'anmen area
With the deepening of the construction of three-dimensional(3D) China,the new fundamental surveying and mapping science and technology continue to develop,and the application is more diverse. The building of a new digital twin city can grasp the regional dynamic information in real time and efficiently serve the city management. Taking the 3D real scene of the infrastructure in Tian'anmen area as the research object,this paper presented the new application scenarios of the new fundamental surveying and mapping in helping regional management from the perspective of implementation methods.
