System of highly detailing map data, server for the same, and method of highly detailing map data

A high-detail map data server for distributing input map data having a data format and a detail level corrected adaptively to a required specification of a distribution destination, comprising:

• a data supplementing unit for supplementing medium-/low-detail map data to make the map data highly detailed;
• an authoring unit for editing the map data adaptively to the multiple required specifications of the distribution destination, which differ at least in one of the data format and the detail level;
• a database for accumulating the map data edited by the authoring unit to allow distribution of the map data as versatile data;
• a data distribution unit for distributing data to the distribution destination;
• and
• a reliability reception unit for registering the reliability in the database in association with the versatile data individually in response to reception of an evaluation from the distribution destination with respect to the versatile data distributed from the database.

A method of highly detailing map data, allowing a computer to execute a program to distribute input map data having a data format and a detail level corrected adaptively to a required specification which differs for each device of a distribution destination, comprising:

• data supplementing step in which a data supplementing unit supplements medium-/low-detail map data to make the map data highly detailed;
• authoring step in which an authoring unit performs an editing process to enhance versatility of the input map data;
• reliability determination step of determining reliability in accordance with a supplementary rate contained in supplementary data used for the data supplementation;
• and
• reliability registration step for readably registering the reliability in the database in association with the versatile data having the versatility enhanced.
