NUMERICAL MAP SYSTEM MODIFING THE DRAWING IMAGE BY GPS

摘要

PURPOSE: A digital numerical map system is provided to combine aerial images and GPS information and draw an image based on a reference point by accurately confirming the position of a boulder in the aerial photograph and checking the reference point. CONSTITUTION: A ground is photographed by a camera(100). A light emitting unit for a boulder is installed at a specific position and emits a laser beam to the camera. A map editor(300) receives a aerial photograph from the camera. The map editor draws the aerial photograph. A reference laser(400) checks the location of the light emitting unit for the boulder.
