The purpose of this paper is to implement of PGIS(Public Geographic Information System) for providing high quality spatial and attribute data through the generalizing process of spatial data. For the operating map data, we improve speed and variable function through the optimization process and we provide easy to use system in searching and analyzing shortest path for the users. Specially, we provide improved searching method and improve speed of analyzing shortest path. Also we enabled the users to analyze data spatially through searching method of spatial area. As a result of the above processing, we provide stable, quick processing speed and variable function.
