Multiple representation database model for real-time synchronization of road networks

Multiple representation methodology is used to display the same real-world-phenomenon at different levels of precision, accuracy and resolution. The primary objective of the this paper is to construct an efficient model for multiple representations which are capable of managing and reconciling real-time data with respect to large-scale roads in Vector Domain. That is to say, we suggested framework based on a bottom-up approach, which is allowed to integrate data from the network of the lowest level sequentially and perform automated matching in order to produce variable-scale map. Finally, we applied designed multi-LoD model to in-vehicle application by using SQLite, which is embedded relational database system, in order to evaluate practical feasibility of the proposed Multi-LoD model and selected Jeju Island as study area and put multi-LoD generation algorithm into real-time synchronization on road networks and dynamic paths finding for on-board map database.
