SPATIAL IMAGE DRAWING SYSTEM CAPABLE OF DRAWING A TOPOGRAPHIC OBJECT OF A REFERENCE POINT OF AN IMAGE WHICH EXCLUDES A COMMUNICATION WITH A GPS SATELLITE FOR CONFIRMING AN ABSOLUTE POSITION OF A POSITION MEASURING UNIT

摘要

PURPOSE: A spatial image drawing system drawing a topographic object of a reference point of an image is provided to minimize an error in a downtown area and to draw an exact topographic object image.;CONSTITUTION: A bottom part of an anchor(131) is cut and a thread(500) is manufactured, thereby preventing a disconnection between a cord(141) and a connecting wire caused by the anchor of a spire type. A ball type weight(600) is detachably connected to the thread. A coupling recess(610) in which the thread is manufactured in an inner periphery is equipped and the thread is thread-coupled to an upper part of the ball type weight. A distribution line path(620) is formed at the center of the ball type weight and passes a wire which is connected with the cord.;COPYRIGHT KIPO 2013
