The Research Of Location And Navigation System Based On GIS/GPS

In recent years, auto industries have already become the pillar industry of our country, it is more and more outstanding that the automobile names function in the daily life and life.How realize all kinds of the effective conductors, coordinate and control and manage and become between communications and transportation and safe one a piece of important problemses who administrative department faces alread of vehicles, according to the statistical data , it is very surprising with the indirect economic losses that the western developed country is because the highway stops up and direct. So in order to satisfy and raise the need which transports efficiency and safety guarantee, the various countries have orientated systematic research to the thing that the vehicle navigates in succession. Behind the reform and opening up to the outside world and with the rapid development Of transportation, how to study a suitable Navigation and Location System for our country Which can satisfy the needs of internal transportation and vehicle management , there are important realistic meaning and economic worth to national economic construction of our country.On the basis of using GIS way ,vehicle navigation and location system incorporate all kinds of technology for locating vehicle position determination optimum road.This paper exemplify the development, construction and reqirment of vehicle navigation and location system and technology of Package type GIS, illustrating the error model of GPS while navigating and describing suitable navigation and location way. On the basis of Electronic map, I have studied suitable map matching algorithms and found a feasible algorithms of erecting Topological construction to attain optimum road, finally using the technology of Package type GIS,I succeed in developing a GIS/GPS location and navigation system.
