Abstract: The information management system includes a first vehicle, a second vehicle, and a center. The information management system manages information provided from the center to a user. The center performs the following processes. The center receives first vehicle information and second vehicle information. The center acquires correction information indicating a difference between the second GNSS position information and the high-precision position information. The second GNSS position information and the high-precision position information are included in the second vehicle information. The center calculates corrected position information indicative of the position of the first vehicle using the first GNSS position information included in the first vehicle information and the correction information. The corrected position information has a higher accuracy than an accuracy of the first GNSS position information The center records the corrected position information.

Abstract: An information management system includes a vehicle and a center. The information management system manages information to be provided to an information utilizer from the center. The vehicle obtains external information by using a capture device recognizing a landmark, obtains location information expressing location of the vehicle, and transmits to the center, vehicle information including the external information and the location information. The center receives the vehicle information, obtains calibration information of the capture device by computation using the external information and the location information and a map information database, and records the external information and the location information and the calibration information.
