The Research Of Relevant Technology Of Automobile Navigation System Based On GPS And GIS

Introduce the navigation system of automobile in application that the research work of this thesis lays particular emphasis on GIS technology mainly, Make the navigation system of automobile utilize GIS strong space and analyse ability besides possessing the general localization function, Can help the driver to show and inquire about and briefed on and choose etc. in the optimum route the automobile position, information in real time , It gets up and finish arriving and avoid traffic jam of letting effectively it ensures traffic safety look for purpose result who status put fast.This text puts forward the key technology involved and put forward the relevant solution progressively according to developping the order of the electronic map system of figure. It probe into organize at what has been lasted map GIS datas, From ones not topological for the the relation one for optimum the searches of the routes , GPS between data processing and interface technology, adopt ComGIS develop mode develop and navigate map the implementation technique relevant content s of softwareAnd the parking stall show that carries on key research and designed in question to plan the route. It studies based on GIS optimum routeses search for algorithm propose information the requests of completeness to GIS relation the structures of form. Good form structure reducible traffic the directionality, turn to , right value finish retraining and search for the complexity brought restraint to the best route s of networks. A different and systematic one hold up foot-path need with visual to take method store topological data by modification corresponding data lists only by issue most,Algorithm ask and solve course keep and become..The influence searched for to the topological relation of network of the traffic and optimum route in change of the real-time traffic information that and has considered. In probing into automobile explain GPS/DGPS make a reservation technology, how import to the computer localization information who GPS/DGPS offer when making a reservation, GPS receiving set and computer and navigate the interface problems of the software; The localization information utilizing GPS/DGPS to offer, is vary and adopted the map to match technology and show the parking stall on the road accurately by the coordinate. Having developed the experimental system at last, relevant algorithm principle and key technology got exactness verification.
