Design And Implementation Of The Digital Village Three-dimensional Visualization System

As further speeds up along with the step of new rural reconstruction in our country, the level of agriculture and the rural informationalization has gradually become a important symbol of country agriculture modernization level and the rural synthesis strength. Digital Rural, as a important component of rural informationalization construction, through the construction of multimedia information networks, geographic information systems and other infrastructure platform, integrated rural information resources, realizes the rural society economy informationalization, has more and more aroused society's interest. At present, our country's GIS development had already formed the quite perfect practical scientific system, WebGIS and 3DGIS becomes the GIS future trend of development. How to realize WebGIS and the 3DGIS effective union, better serves the digital rural project, this thesis combines the three-dimensional visualization system of Digital Rural design and realize, has made certain research to the above question.At the conclusion of theoretical studies,based on the characteristics of Digital Rural, this thesis proposed taking Skyline as the re-development platforms and developing the three-dimensional visualization system of Digital Rural; making the detailed research and exploration to the rural three dimensional landscape model construction; in the solution modeling foundation, successfully realizing several basic function, such as three-dimension map roaming, localization and navigation, area measurement, information inquiry and so on; Optimize layers management, significantly improving data transmission efficiency and shortening the browser deal time; the implementation of the two-dimensional map and three-dimensional map linkage function, enhancing the system interoperability with the affinity, causing a more widespread popularization of system's management and use.The theoretical research and practical experience of the thesis has played a positive role in the depth study at WebGIS and three-dimensional visualization, provided practical methods and reference mode for the combination of WebGIS and 3DGIS; carried exploring experiment in the realization of the rural informationalization; provided a reference basis for the future Digital City's establishment.
