The left diagram shows a ranking from relatively less noise problems perceived down to cities with highly perceived noise problems (dataset 2). The right diagram shows in addition the reported noise data under the Environmental Noise Directive 2002/49/EC (dataset 1). The colour of the city names indicates if the population moves rather towards the centres or to the edge or develops similarly in the centre and the edge (dataset 3)

The figure shows the flooded area in Dresden during different flood events
The map shows the relation of green urban areas to the green background, i.e. it compares the mean value of green background of the city surroundings with the mean values of green urban areas of the core cities, both in [%]. Results are represented by points of different colours.
Quiet areas decided by the the city of Oslo and the connection between areas
Three different groups of regions can be distinguished: (1) heavily urbanised regions with a population density higher than 100 inhabitants per km2; (2) ex-urban, generally semi-rural, beyond the suburbs of a city, but experiencing major urban influences such as commuting, and semi-rural regions; (3) rural and remote regions.The heavily urbanised regions have an effective mesh density above 100 meshes per 1 000 km2. On average, these regions are 40 times more fragmented than ex-urban ones. Ex-urban regions have an effective mesh density between 20 and 100 meshes per 1 000 km2. On average, this group is 15 times more fragmented than agricultural (rural) regions. This last group of regions has an effective mesh density ranging from 0.2 to 20 meshes per 1 000 km2.
