In a method and apparatus for the management of data, particularly coordinate data, which are determined with respect to a number of predetermined reference points with a spatial distribution around the respective reference points using at least one sensor arrangement, such as a coordinate determination arrangement, the data points are grouped into a number of classes in accordance with a first distance criterion, a respective center point of the data point classes is determined, a distance of each data point from the center points of the data point classes is compared with a second distance criterion, and the various individual data point classes are assigned to respective reference points.
