A SYSTEM UPDATING DIGITAL MAP MAKING

摘要

PURPOSE: A digital map height error confirmation system through the precise interpretation of precise DSM and DTM information and ground information is provided to automatically perform an altitude correction through a connection pipe by transmitting a control signal to a pulley in consideration of the extended distance of the connection pipe in an altimeter controller. CONSTITUTION: A digital map production server(100) performs the storage of an picture image and a drawing image, the synthesis and editing of the image, a GPS(Global Positioning System) coordinate synthesis, and the making of the drawing image. An altitude adjustment unit(300) is combined with the other end of the screw of a photographing unit(200). An altitude measurement controller(400) performs a GPS coordinate sensing, a GPS coordinate reception, an altitude adjustment, and the transmission of an altitude measurement. The altitude adjustment module of the altitude measurement controller adjusts an error between the position and altitude of a camera unit.
