Development of "three-dimensional real scene" work in China
This paper introduced the background of the "three-dimensional(3D) real scene" policy,and it summarized the standard establishment,software development and application of "3D real scene" at national and provincial levels,as well as the national pilot situation. The 3D real scene standard system has started to construct,with more standards at local and group levels,and fewer standards at national and group levels.The standard names of 183D real scene was provided,which required approval but have not been approved. A large number of excellent 3D real scene software was developed,providing tools and technical support for the construction of 3D real scene China. All the pilot units have established the technical scheme of data acquisition and modeling,which forms a series of 3D real scene products. They developed the related digital space base and applied it in different fields.Similarities should be summarized to avoid repetitive work.The mechanism of labor division was established so that the division fruits cover all the technical content of 3D real scene.The technology and theory system began to take shape. However,there are still gaps in the intelligent acquisition,processing and service of 3D real scene data. The transformation from traditional four-dimensional(4D) products to 3D geographic entity data requires further breakthroughs, and the method of collecting 3D data from multiple sources urgently needs to be promoted in practice.
