1. A communicative navigation system comprising:

  • an information distribution server having a cartographic database for storing cartographic data for route searching, and a mesh database whereby images produced from aerial photographs or satellite photographs are partitioned and stored in meshes for each prescribed region; and

    a mobile navigation terminal connected to the information distribution server via a network;

    wherein the system is characterized in that the mobile navigation terminal has a GPS processing means for determining a current location, a matching processing means for matching a measured location with a route to determine the current location, a mesh data request processor for computing mesh data wherein a new distribution request for mesh data containing the current location is sent to the data distribution server, and an operating unit for inputting route search parameters, and which sends distribution requests for route search parameters and/or mesh data to the information distribution server;

    wherein the information distribution server is provided with a route search unit and mesh data distribution unit, and searches routes using the cartographic database for route searching, and, when the route guidance requested for distribution is in the form of mesh data, adds the route guidance data to the mesh data and sends the integrated data to the mobile navigation terminal; and

    the mobile navigation terminal displays the route guide on the distributed mesh data.
