摘要
本文以机场反劫机为例设计了一种城市重要目标反恐战场环境的三维可视化和查询工具。该工具将虚拟环境中的地理要素以三维和二维的图形、图像表达出来,主要采用边界模型作为建立3维目标的数据结构,并利用DDE技术连接三维场景中的景物和二维GIS的关系数据库存储属性并实现查询功能。其特点是利用简单的DDE方式实现了3D场景数据和属性数据双向查询,充分利用了已经建成的2DGIS的成熟功能和现有资源。
In this paper, a tool that can effectively visualize and query 3D city models is presented. The tool has realized the combination of 3D vision simulation and two-dimentiona1 GIS. With boundary model as 3D object data structure, and DDE as connection technology, this tool has realized 3D and 2D GIS storage and search function. Its main characteristic is that it can perform bi-direction search between 3D data and feature data and has made full use of 2D GIS mature function and technology.
