基于Skyline的三维数字城市研究与应用
|
摘要
当前大多数的WebGIS主要还是以二维的形式表现,而实现地理信息系统的三维可视化,将Web技术、GIS技术、三维建模技术和地形数据的结合应用是今后地理信息系统发展的趋势和核心。对此,采用了Skyline平台和ArcGIS平台,进行三维数字城市的研究。根据Skyline平台的地形处理、三维模型处理、三维场景的快速浏览以及三维地图信息发布的优势,以及ArcGIS平台的二维数据制作、数据处理和空间分析的优势,采用WFS规范发布二维地图服务和空间分析服务,通过空间属性和空间数据引擎技术实现二、三维的同步,实现了三维数字城市。通过采用具体的实例对三维漫游、三维查询、三维分析等功能进行验证,所实现的功能在极大程度上满足了三维数字城市功能的需求,为三维数字城市的研究和应用提供了一种技术方法和技术参考。
At present,most WebGIS are mainly presented in two-dimensional form. The realization of three-dimensional visualization of geographic information system and the combination of Web technology,GIS technology,three-dimensional modeling technology and terrain data are the trend and core of the development of geographic information system in the future. Therefore,we adopt Skyline platform and ArcGIS platform to study 3D digital city. According to the advantages of terrain processing,3D model processing,quick browsing of 3D scenes and publishing of 3D map information based on Skyline platform,and that of 2D data production,data processing and spatial analysis based on ArcGIS platform,2D map service and spatial analysis service published by WFS are adopted,and the spatial attributes and spatial data engine technology is used to achieve two,three-dimensional synchronization,to realize the 3D digital city. By using concrete examples to verify the functions of 3D roaming,3D query,3D analysis and so on,the functions realized meet the needs of 3D digital city to a great extent,which provides a technical method and technical reference for the research and application of three-dimensional digital city.
