METHOD FOR GENERATING SURFACE COORDINATE MAP, METHOD FOR PROVIDING GEOGRAPHIC INFORMATION USING SAME, AND METHOD FOR PROVIDING ROAD GUIDING INFORMATION

摘要

Disclosed is a method for generating a surface coordinate map. The method includes the steps of: storing, by a surface coordinate setting unit, unit surfaces each of which is divided into multiple horizontal lines and multiple vertical lines in a database as surface coordinates; determining, by a feature point coordinate acquiring unit, a corner point and the most outer point as feature points in a plane figure of a subject area and acquiring GPS coordinates for the feature points; inputting, by the feature point coordinate acquiring unit, the GPS coordinates for the feature points into the surface coordinates; connecting, by a mimetic diagram generating unit, the GPS coordinates for the feature points on the surface coordinates to acquire a mimetic diagram for the subject area; and determining, by a surface coordinate map generating unit, the surface coordinates including areas of the mimetic diagram as surface coordinate groups of the subject area and storing the surface coordinate groups in a database to generate a surface coordinate map for the subject area.;COPYRIGHT KIPO 2015
