Times series for <i>T = 4.5</i> showing the number of clusters generated at each scale.

As the scale increases, the number of cluster between time periods became more and more stable, because the urban structures became undistinguishable from each other at larger scales. At scale 10, we have only two big clusters representing the whole study area at any time period. Times series for T = 4.5 showing the number of clusters generated at each scale.
