Abstract:	GIS is an essential part in modern In-Vehicle Navigation System. To apply GIS in Navigation system means not only to improve precision of navigation system but also to bring visual and humanized navigation environments. The objective of this work is to study the model and construction of IVNS-Oriented GIS. The research is mainly focused on how to organize information useful for functions, such as Map-Matching, Road Guidance, and Optimal Path Finding, in in-vehicle navigation system. Firstly, the required information of IVNS to GIS is stated. Then, a novel single-lined road network model based on road-node-connection is presented, and this model can well represent real-world road networks. OO Technique is adopted to represent geographical entities and their properties. All information is organized in Relational Database, which is quite different from the implementation of conventional hybrid GIS. With database engines and OO program languages, such as C++, the performance of RDBMS can be greatly extended. This can resolve the problem that RDBMS can not treat real world with OO method and OO languages lack the ability to keep objects persistent. In Object-Relational model, the mapping of objects to relational tables and the reverse process are stated. A more powerful IVNS-Oriented GIS is constructed based on this model. Prospect on development of future Navigation-Oriented GIS is given at last. KEY WORDS: IVNS, GIS, OO, RDB, Object- Relational Model
