Preliminary Study on Conception and Key Technologies of the Location-based ParrInformation Map

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 Parrlocation 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 location，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.
