Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a mobile apparatus, a geographical information system and a method of acquiring geographical information, and more particularly to those acquiring related geographical information and services by a geographical object message. 
       BACKGROUND OF THE INVENTION 
       [0002]    As our living standard improves drastically in recent years, people pay more attention to leisure activities, and taking a trip becomes one of the major leisure activities. To ensure consumers to have a successful trip, various different means are developed, such as global positioning system (GPS). GPS was originally intended for military purpose, but now it is used extensively in civil navigation due to its practicability. On the other hand, consumers who go out for a trip generally need a tourist guide for providing information on scenic spots and related routes. 
         [0003]    A terminal of a conventional global positioning system can position an object or a place on a map based on the wireless signal from a plurality of GPS satellites and provide a map related hint function, wherein the hint function produces a hint signal for each location by comparing a positioning signal and a data stored in the terminal and displays the hint signal on the map. 
         [0004]    Although the conventional global positioning system can provide navigation and positioning functions, users cannot acquire their desired information from a direct viewing. In view of the shortcomings of the prior art, the inventor of the present invention based on years of experience to conduct extensive researches and experiments, and finally developed a mobile apparatus, a geographical information system and a method of acquiring geographical information in accordance with the present invention. Derived from the traditional concept of hinting a fixed point, the present invention provides users the required geographical information. Therefore, a user taking a trip no longer needs the service of a tourist guide to enjoy the scenic spots, and the present invention definitely improves the degree of freedom of a trip and effectively manages personal time. 
       SUMMARY OF THE INVENTION 
       [0005]    An objective of the present invention is to provide a mobile apparatus, a geographical information system and a method of acquiring geographical information, and more particularly to related geographical information and services acquired by a geographical object message. 
         [0006]    To achieve the foregoing objective, the invention provides a geographical information system for acquiring geographical information of a geographical object, and the system comprises a geographical object message and a mobile apparatus, wherein the geographical object message is provided by the geographical object, which is usually an identification code or an image. After the mobile apparatus receives and identifies the geographical object message, the mobile apparatus generates an inquiry command. The geographical information corresponding to the inquiry command is searched from a database of the mobile apparatus based on the inquiry command to display the searched geographical information on the mobile apparatus. 
         [0007]    To achieve the foregoing objective, the present invention also provides a geographical information system for acquiring geographical information of a geographical object, and the system comprises a geographical object message, a mobile apparatus and an information center, wherein the geographical object message is provided by the geographical object, and can be an identification or an image. After the mobile apparatus receives and identifies the geographical object message, the mobile apparatus generates an inquiry command, and sends out the inquiry command by a communication module of the mobile apparatus. After the information center receives the inquiry command, the information center searches the geographical information corresponding to the inquiry command and sends the searched geographical information to the mobile apparatus for display. 
         [0008]    To achieve the foregoing objective, the present invention further provides a mobile apparatus comprising a device body, a database, a capture identification module, a communication module and a processor. The device body provides basic operating functions for the mobile apparatus, and the database, the capture identification module, the communication module and the processor are installed in the device body. The database stores the geographical information of at least one geographical object. The capture identification module acquires the geographical object message of the geographical object from outside and identifies the geographical object message to generate an inquiry command. The communication module is provided for sending the inquiry command and obtains the geographical information from outside. After the processor receives and processes the inquiry command, the processor transmits the inquiry command to the database to search the geographical information corresponding to the inquiry command, or the processor transmits the inquiry command to the communication module. 
         [0009]    From the foregoing objective of the present invention, the invention derives a method of acquiring geographical information that is applied to a mobile apparatus for displaying geographical information, and the method comprises the steps of: acquiring a geographical object message of a geographical object from outside; generating an inquiry command after the geographical object message is identified; searching geographical information corresponding to the inquiry command from a database based on the inquiry command or searching geographical information corresponding to the inquiry command from an information center based on the inquiry command; and displaying the geographical information on the mobile apparatus. 
         [0010]    In summation of the description above, the present invention adopts the geographical object message to provide a direct viewing of the user&#39;s required geographical information and related services, and improve the degree of freedom of a trip and effectively manage personal time. 
         [0011]    To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.
