摘要
随着移动定位技术的飞速发展,追踪移动对象以提供定位服务(location-based services,LBS)已变得切实可行。一般地,定位服务器被构建为一个移动对象数据库。主要讨论在移动对象数据库中查询时空数据的相关核心技术,包括数据模型、索引结构。并给出了一种可用于LBS环境下的相关实现。
With the growing advances of positioning technologies, tracking the location of mobile objects to push Location-Based Services (LBS) has been applicable. Generally, the location server is constructed as a Moving Objects Database (MOD). In this paper, the key technologies of querying spatial-temporal data in MOD are presented, including data model and index structure. Such technologies are discussed and analyzed in detail, and the relative proposal for LBS is given.
