Method and device for correcting a digital map

The method for correcting a digital map comprising the following steps:

• carrying out a calibration phase including the following steps:
• selecting a first map section of the digital map,
• checking the first map section for errors and correcting the errors found in the first map section in a first correction stage,
• checking the corrected first map section for errors and correcting the errors found in the corrected first map section in a further correction stage,
• repeating the further correction stage until fewer than a predetermined number of errors are found in at least two successive correction stages, as a result of which a first number of correction stages of the first map section from the calibration phase is ascertained;
• ascertaining a second number of needed correction stages for remaining map sections of the digital map based on the first number of correction stages implemented in the calibration phase for the first map section, wherein the second number of needed correction stages is at least one correction stage less than the first number of correction stages implemented in the calibration phase;
• and
• checking and correcting the remaining map sections of the digital map with the ascertained second number of correction stages.
