Onboard information terminal and map information providing apparatus and map information providing system using them
First Claim
1. An onboard information terminal comprising:
- a map information storing section for storing map information;
a distribution information acquiring section for obtaining, from outside, distribution road information containing coordinate point string data consisting of a series of coordinate points indicating geographical positions;
a road data generating section for generating, in the same format at least in part as the map information, road data for adding a new road to a road network, which is represented by the map information stored in said map information storing section, from the coordinate point string data contained in the distribution road information obtained by said distribution information acquiring section; and
a map information update section for generating new map information from the road data generated by said road data generating section and the map information stored in said map information storing section.

Abstract
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.
