PURPOSE: A geographic survey confirmation method for numerical map production and real time update of geographical information are provided to implement more exact map information of GIS server by designating a section in which real measurement is required through the comparison between an estimated distance of one point and another point and an average vehicle moving distance. CONSTITUTION: A worker inputs a vehicle moving distance to a terminal controller(230). The terminal controller recognizes a close location as a new restart location. The terminal controller recognizes a start location as a new re-close location. The worker inputs a vehicle reverse moving distance to the terminal controller. The terminal controller transmits location signals through wireless communications. If the error value between an estimated distance and an average distance is not a reference value scope, a GIS(Geographical Information System) controller(320) designates the corresponding section as a real measurement requirement section. |
