Abstract

A server specifies a sending range for meteorological information that it has received, for each type of meteorological information. The server also specifies constitution and size of area meteorological data distributing for each area segment. This will enable the server to provide necessary meteorological information more efficiently. Furthermore, a vehicle-mounted navigation apparatus, or a vehicle, selects and specifies different meteorological information for a corresponding area segment based on present position and route, and specifies the constitution and the size of area meteorological data requesting distribution, by the server. It is expected that this can reduce the data size of meteorological information and prevent unnecessary information from being distributed, enabling savings in communication time and communication charges when data is received.
