Abstract: A method for correcting a digital map. The method includes: carrying out a calibration phase including: 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 based on the first number of correction stages implemented in the calibration phase for the first map section.

Abstract: A method for creating a map. In the method, first, sensor data from a predetermined number of passes through a portion of a space are read in. Next, features in the sensor data are identified, wherein the features are identified separated onto multiple spatial regions of the portion of the space. The features are also assigned to a sensor position. Then, accuracy values for the features are ascertained, and each spatial region is assigned an accuracy value. Lastly, the map including the features related to sensor positions and the accuracy values of the spatial regions is generated.
