基于地理信息系统的虚拟战场态势显示

以分布交互仿真中的虚拟战场态势显示为需求背景，基于地理信息系统(GIS)的理论和相应的软件工具，在虚拟战场态势显示中引入GIS技术，实现了基于GIS的虚拟战场态势二维与三维、静态与动态的显示，以及战场数据的添加与查询，计算机生成兵力的初始化及实时驱动、飞机地形高程匹配飞行的三维仿真。开发了一个具有统一集成环境、二维与三维态势显示相对应等特点的原型系统。 并介绍了其组成、功能和特点。

Visualization of Virtual Battlefield State Based on Geographic Information System

The background is visualization of virtual battlefield state in distributed interactive simulation system. Based on the theories of Geographic Information System (GIS) and softwares related, it is realized the display of two dimensional state and three dimensional state as well as static state and dynamic state in the virtual battlefield, the adding and inquiring of information, the initialization and real-time driving of Computer Generation Force, and the airplanes flying with terrain matching of elevation. A prototype system is built up, which has integrated environment and shows three-dimensional state corresponding to two-dimensional state and other characteristics. Then, the structure, functions and features of the system are illustrated.
