摘要:For 3D city management visualization, query and the analysis of 3D data related to cities are very important tasks. In this paper, we present a tool (3D-City VAQS/ 3D-City Visualization Analyse and Query System) that can effectively visualize and query 3D city models. We use relational database model to represent geometry and topology of 3D city data. We organize 3D data in layers and themes and each theme has their own attribute tables. Our tool provides to query both geometry and attribute information of 3D data. We use V3D data structure and implement it in a relational database
