MAP DATA UPDATING SYSTEM FOR CONFIRMING TOPOGRAPHY CHANGE BY GPS COORDINATE DATA

摘要

The present invention relates to a geodetic measurement data updating system for confirming the topographic change by GPS coordinate data, capable of providing a self-generation type apparatus for concealing reference points and performing external operations using the speeds of vehicles driving along a corresponding road, based on the fact that many reference points for geodetic measurement are installed on general waysides, and obtaining accurate air and ground video images based on GSP coordinates by reference points using the apparatus and then utilizing the obtained images to update the geodetic measurement data. According to the present invention, the geodetic measurement data updating system for confirming the topographic change by GPS coordinate data comprises a Self-generation unit, a protective case, a cover opening and closing device, guide rails, an elevating power supply cylinder, a base plate, a reference point body, a transmitter, a transmitter control unit, a receiver, a main processor, a GPS unit, a camera, a receiving unit, a photographing control unit, a numerical map manufacturing device.
