Web-based dynamic visualization of 3D spatial data

Abstract

Abstract True 3D GIS requires lot of efforts from GIS research community both in academia as well as from software vendors. Visualizing 3D spatial data from DBMS for such 3D system is one of the issues and problems in 3D GIS domain. This paper discusses the dynamic visualization of 3D spatial data such as buildings and other large objects using geo-DBMS couples with Web that works with VRML and X3D modeling languages. The modeling of the 3D objects are based on the Simplified Data Model (SDM). The experiment will be presented by using digital 3D building datasets and the approach is applicable for tasks like 3D strata title and buildings management. Finally, it discusses the limitations and shortcomings of the current approach, and identifies future research and development tasks. Key words: 3D spatial data, VRML, X3D, visualization, and GeoDBMS.
