摘要
本文对试验场中三维GIS实现方法进行探讨,从试验场对三维GIS的实际需求出发,设计了一种新的基于Unity3D平台的三维GIS系统体系结构,并实现了三维数据的组织、查询和显示,解决了属性数据和空间数据的有效连接、多媒体信息组织与管理、海量数据的存储、虚拟现实技术的实现等技术难题。
This paper discusses how to realize 3D GIS in testing ground. Based on the merits of Unity 3D, this paper development the 3D GIS system on the Unity 3D platform for the first time, the system has been achieve the basic function and put into use, the function include 3D terrain mapping, 3D entity model loading control and man-machine interactive roaming etc, which fulfils the users requirements. Because of the easy operating, the good compatibility, expansibility and inexpensive, and the autonomous applying, the system can adapt to many different areas of application and has a broad application promotion prospects.
