摘要：
A map information providing system has a map information providing apparatus 1 and an onboard information terminal 3. The map information providing apparatus 1 selects a road represented by the coordinate point string data indicating a newly established road in accordance with distribution request information obtained from the onboard information terminal, and distributes the distribution road information containing the coordinate point string data about the road selected to the onboard information terminal. The onboard information terminal obtains the distribution road information containing the coordinate point string data from the map information providing apparatus, and generates, in the same format at least in part as the map information, road data for adding a new road to a road network represented by the map information stored in a map information storing section from the coordinate point string data contained in the distribution road information obtained, and generates new map information from the road data and map information.
