Design and Realization of Thematic Mapping in Web3DGIS

摘要

thematic mapping is an important module of GIS. With the development of technology such as 3D visualization and network communications, how to realize and optimize the thematic mapping based on Web3DGIS has become a hot research topic of GIS. This article has designed and realized a Web3DGIS platform based on Rich Client/Server, and adopted a thematic mapping method based on geometry. Through the method level-3 cache mechanism, the render efficiency of thematic mapping in the 3D scene and its expression ability has been effectively improved which has verified the feasibility of this method.
