PURPOSE: A numerical map correction system is provided to offer accurate topography information through the real time correction of a numerical map about a topography which is temporarily or enduringly changed. CONSTITUTION: A numerical map correction system is composed of a producing part(100), a fence(200), and an information originating part(300). The producing part is installed in a vehicle and has a navigation function. The producing part comprises a map database(110), GPS(120), a drawing module(130), a receiving module(140), a revising module(150), and an output module(160). The fence is installed in order to divide a specific area. The information originating part confirms the range of an area which is divided by the fence while communicating with the fence. The information originating part transfers location information. |
