基于Web Services的三维空间数据表达与传输研究

随着地理信息系统应用的日益普及,它已渗入各个领域,人们对其技术需求也不断提高。以往单机版的2DGIS不能满足人们应用的要求,而3D的网络GIS成为大众关注的焦点。目前,3DGIS和WebGIS都得到了广泛的研究,形成了一定的理论研究成果。但是,这两种技术相结合的研究还很少。本文在以往形成的WebGIS理论基础之上,将之与3DGIS相结合,探讨了一种基于Web Services实现网络三维空间数据的表达与传输服务的方法,并通过实验来验证了这种方法的可行性。

Research on expression and transmission of 3D spatial data based on Web Services

As the Geographic Information System (GIS) being increasingly universally applied, it has permeated into each field new.People's demands for its technique have increased continuously.The conventional 2DGIS which was running with the single computer can no longer satisfy people' s request, and 3DGIS deserves serverely concern.Nowadays, 3DGIS and WebGIS have been researched universally, and have formed a certain academic achivement This paper put forward the method to realize 3D visualization in network based on Web Services with the foundation of the theories developing in WebGIS and 3DGIS area, and then verified the possibility of this method in the way of making an experiment of releasing the expression and transmission of 3D spatial data.
