摘要
A search oriented geographic information system (GIS) includes a hand held input display process unit which couples with a global position system (GPS) for displaying road map menu on a display screen for user selection and use. A global system for mobile communication (GSM) is used to transmit vehicle location coordinates data and user selection item through the GSM base stations to a GIS server which processes the receiving data and produces output results for transmitting back to the input display process unit through the GSM for user to get the most updated road and street map information around the vehicle.
