Ulm: city in Baden-Württemberg, Germany
What exactly constitutes the spatial extent of the city? For these aggregations, we used the Global Human Settlement Layer Urban Center Database (GHS-UCDB) to define the boundaries of the city. These cities -- or urban centers -- cover areas that are densely populated and built-up, and so may extend beyond the spatial borders of these cities that we may be familiar with. The GHS area is shaded in blue.

Effect on the aggregate network: New construction in each period adds to the total stock of streets, but does not change streets that have already been built. Therefore, it has a limited effect on the street network as a whole. The SNDis of the aggregate street network in the respective time periods are 0.72, 0.84, 0.85 and 0.88. Overall, the SNDi of the aggregate street network has risen: the street network in Ulm has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.12 points, but between 1991-2000 and 2001-2014, it rose by just 0.04.
