A method for determining a global position of a first landmark is provided, wherein at least one first and one second measurement data set are recorded. A first reference point and a first recording space are assigned to the first measurement data set, and a second reference point and a second recording space are assigned to the second measurement data set. A spatial correlation of the first and second landmark relative to each other is determined using the first measurement data set. The global position of the first landmark relative to a global reference point is determined by determining a first and second relative position of the first landmark, by determining a first relative position of the second landmark, and by using the determined spatial correlation.
