Abstract
A map data correcting method for correcting map data used in a vehicle using a controller includes executing a first correction process of uniformly offsetting the map data as a whole to reduce a first error that is a general position error of the map data and executing a second correction process of reducing a second error that is a position error still remaining in the map data even after uniformly offsetting the map data as a whole.
