| Abstract: | This paper introduced current researches on Web 3D-GIS in brief.After that,the paper designed a three-tier architecture for Web 3D-GIS,which includes data tier,publishing tier and application tier.According to it,the technical route based on Skyline software was elaborated.Moreover,the paper showed the specific construction steps that are data acquisition,data processing,system development and release & deployment.Then,some measures to optimize actual construction process in terms of 3D model building,model displaying,data loading and cache setting were provided.At last,a lot of disadvantages as deficient expansibility,huge difficulty of data update and nonsupport for spatial analysis were pointed out by analyzing the practical application case.The paper claimed that the development direction and trend of Web 3D-GIS could be to apply the standard of HTML 5 and 3D structure feature,which would promote the progress of 2D & 3D integration. |
