Information Visualization Design Of Location-based Pan-information Map In Mobile Terminal

As the transmission carrier of geo-spatial information and location service information,the map has new requirements for its information visualization design in the new era.In addition to satisfying human needs for spatial cognition,the visualization of maps should also provide intelligent and individualized location services.The location-based pan-information map comes into being in the demand of the information age.It is an intelligence service platform that is based on the location as the bond,dynamically associates of things or events in the omni-directional information,and provides personalized location and related position.Based on the information visualization design of geographic location,this paper constructs the research framework foundation of the whole subject and uses the Location-based Pan-information Map of mobile terminal as the design carrier.At first,the literature research method is used to analysis and research the visualization design of mobile Location-based Pan-information Map information in this paper.Through the analysis,the specific content and design requirements of the information visualization design of Location-based Pan-information Map are clarified,and the theoretical basis of the situation,cognition and map design for the visual design of mobile terminal holographic map information is summarized.Secondly,the logical research method is used to logically analysis every information elements of Location-based Pan-information Map,in order to find out the corresponding relation between user demand and information data structure.The content of information visualization of mobile Location-based Pan-information Map both includes the selection and determination of location services,and the rational combination of geographical information elements.The basic elements that represent the content of objective geospatial information in the mobile holographic position map,as well as the thematic superposition elements of subjective information content such as user demand,time,space situation and so on,the reasonable planning and arrangement of logical relationship between those factors,present in the visual space of mobile terminal in the way of information visualization.The study of the logical relationship between information elements,provides the basis for the design of adaptive visualization of mobile terminal map information,and then lay the foundation for auniversal information visualization application model.Finally,the model research is used to summarize and conclude the relationship between the design of information visualization and the visual expression factors of the mobile Location-based Pan-information Map.Based on the analysis of influencing factors such as user information,situation and screen size of the display equipment,the decision-making model of position map visual content selection decision model that help people make spatial behavior decisions is established.Depending on the triggering and operation mechanism of map elements of the mobile Location-based Pan-information Map,this paper builds the holographic mobile location information visualization expressing strategies.Appling the model and theory to the design practice,as the basis and direction to guide the product optimization of the location map of mobile terminal,has certain theoretical significance and potential application value.
