PROCESS FOR INPUTTING STARTING AND DESTINATION POINTS INTO NAVIGATION SYSTEMS

摘要

In a process for inputting starting and destination points into an electronic navigation system for motor vehicles, relevant road map data, including a street identification and supporting point co-ordinates with corresponding house number, are stored in a memory. After the street identification and house number of the starting or destination point are input, the memory first searches the street identification and then the house number. If the input house number matches the house number of a supporting point in the memory, the co-ordinates of said supporting point are adopted for navigation. If the event of non-matching, the neighbouring supporting points in the memory are determined and the co-ordinates of the starting or destination points are determined by interpolation and used for navigation.
