Abstract
The present invention provides a map error information obtaining system which can promote the collection of the map error information as well as reduce the number of man-hours required for researching the site and verifying whether or not the collected map error information is accurate. The map error information obtaining system herein disclosed comprises a position detecting apparatus including image obtaining means for obtaining image data indicative of an actual condition of and in the vicinity of a current position, and a center apparatus, the position detecting apparatus being operative to transmit map error information including a position of the map information and image data where it is judged that there is a difference, to the center apparatus. The center apparatus is operative to correct the map information after verifying whether or not the difference in the map information is accurate using the image data. Furthermore, the center apparatus is operative to calculate an evaluation point for each of the position detecting apparatuses which have transmitted the map error information so that operators operating the position detecting apparatuses can be rewarded in accordance with their evaluation points.
