摘要
导航数据库(Navigable Database)是指针对智能交通系统与定位服务应用需求而建立的具有统一技术标准的地理数据库。本文对导航数据与一般的地理信息数据在数据模型、数据的准确性、数据的组织方法等方面进行了比较。在简要介绍导航数据库概念后,讨论了城市交通系统中导航数据的来源及导航数据的处理理论。
The navigable database is the geographic database with uniform technical standards to satisfy the requirement of intelligent transportation system and location based service. This paper compared the navigable data with general geographic information data in data model, accuracy and structure, etc. It also introduced briefly the concept of navigable database and discussed the source of the navigable data in the city transportation system and the theories of navigable data processes.
