针对在泛在信息与大数据时代下,传统数字地图存在的局限性与面临的挑战,本文在原有概念基础上,拓展了全息位置地图概念内涵,即在泛在网环境下,以位置为纽带动态关联事物或事件的多时态(multitemporal)、多主题(multi-thematic)、多层次(multi-hierarchical)、多粒度(multi-granular)的信息,提供个性化的位置及与位置相关的智能服务平台;基于上述内涵,本文阐述了全息位置地图的重要组成与特征,并就泛在信息获取、语义位置关联和多维动态场景构建与表达等3个方面的关键技术进行了探讨。
This paper analysis the limitations and challenges of the traditional digital map in ubiquitous information and big data era. We extend the original concept of a Pan-location Information Map (PLIM) that in the ubiquitous network environment. PLIM dynamically associates mutli-temporal, multi-thematic, multi-hierarchical, multi-granular information about objects or events based on loca- tion, and provides a personalized location and location-related information service platform. Also, we describe the structure and characteristics of a new PLIM and demonstrate the key technologies in three aspects, including ubiquitous information acquisition, semantic location correlation, and establishment of a multi-dimensional visualization map.
