Management of complex three-dimensional scene is the basis of3 DGIS, three-dimensional landscape system and virtual reality.
三维复杂场景管理是三维地理信息系统、三维景观系统、拟现实的基础和核心。
Since DGIS service system is a very complex system, a prototype implementation based on Java technologies has been developed.
由于DGIS服务系统是一个非常复杂的系统，我们开发了一个简单的原型系统。
At the same time, the DGIS can be applied in many fields, such as agriculture, forestry, ocean, environment, traffic, communication, urban construction, education and military, etc.
同时，分布式地理信息服务的应用范围非常广泛，可以应用于农业、林业、海洋、环境、交通、城市建设、通讯、新闻媒体、教育以及军事等几十个领域。
The feature of DGIS is huge amount of space and information data, complicated function of management and query, the requirement of system openness and the tight combination with DMS and SCADA, etc.
DGIS具有空间数据和资料信息量大，管理查询功能复杂，系统开放性要求高，同配电管理系统（DMS）、SCADA系统结合紧密等特点。
