used threshold value of 2.5 m and the influence of this threshold value are illustrated in
Figure 7 for the sample data set. In addition to the used threshold of 2.5 m, binary maps
are also illustrated for less ideal thresholds. In the case of a low threshold of 1.0 m, too
much noise is present in the change map. In the case of a high threshold of 5.0 m (parts of),
changed buildings are not detected in the change map.
