基于位置信息的自适应地图服务技术

ADAPTIVE MAPPING SERVICES TECHNIQUE BASED ON LOCATION INFORMATION

分析自适应LBS(Location-based Service)服务的主要特征,以及以用户为中心的突出个体感知的智能LBS的关键技术。主要讨论能够满足用户个性化定制的自适应的地图服务的关键技术:位置感知计算、事件驱动、参考坐标系的转换以及自适应的平移、旋转、放大和缩小等。

The main characteristic of adaptive LBS services is analyzed, and the key technique of user-centred egocentric awareness-highlighted intelligent LBS is discussedThe essential arguments are put on the key techniques of adaptive mapping services satisfying the individual customization for users, including location-awareness computation, event-driven pattern and reference coordinate system transformation, as well as the translation ,rotation, amplification and reduction of self-adaption.
