LOCATION INFORMATION PROCESSING SCHEME AND A HANDLER BASED ON GROUP MANAGEMENT FOR A LOCATION-BASED SERVICE, CAPABLE OF MANAGING A POSITION GROUP OF VARIOUS LOCATIONS AT THE SAME TIME

摘要

PURPOSE: A location information processing scheme and a handler based on group management for a location-based service are provided to correct error location information by using common differential information which is applied to the position of different spots at the same time.;CONSTITUTION: A first road information extraction unit(210) extracts first road information which is adjacent to the first location information. A first differential information operation unit(220) respectively calculates the differential information between the first road information and the first location information. A second road information extraction unit(230) extracts the second road information which is adjacent to the second location information. A second differential information operation unit(240) calculates the differential information between the second road information and the second location information. A third road information generator(250) generates the third road information corresponding to the third location information. A reference variation information extraction part(260) extracts the standard variation information from the third road information.;COPYRIGHT KIPO 2010
