HEIGHT ERROR CONFIRMING SYSTEM OF NUMERICAL MAP BY PRECISION ANALYSIS GSP INFORMATION

摘要

PURPOSE: A digital map management system in a detail composition method of a GPS(Global Positioning System)-based picture image through digital information confirmation is provided to update a digital map manufactured based on data having an error, thereby increasing the accuracy of geographic information included in the digital map. CONSTITUTION: A reception sensing module(130) is fixed by fixing bars(500) extended from a guide(154). A second communication module(120) is placed to cover the reception sensing module with a protruded fixing piece(510). The protruded fixing piece is connected with a lift bar(153) to be fixed. A height adjustment bar is inserted into supports.
