The Kalasatama study area is mostly situated in the inner transit fabric whereas the Kuninkaantammi study site is located in the outer autobile fabric. In 2030 the southern parts of Kuninkaantammi will be part of the outer transit fabric. Not much change will have happened in the Kalasatama study site. The urban fabrics in Kuninkaantammi will not change between 2030- 2050 whereas the southern parts of Kalasatama, especially Sompasaari, will become inner and outer transit fabric. The map includes the urban fabrics in 2016 and the areas suitable for recreation in 2018. The dataset includes recreational areas that are 1,5-20 ha in size (Source: Corine 2018, Kopperoinen et al. 2012) The map includes the urban fabrics in 2030 and the areas suitable for recreation in 2018.

Only Euclidean commuting distances below 100 km are included in the calculation. People commute to Kalasatama from all over Helsinki, with an emphasis on southern and eastern Helsinki areas. Compared to Kuninkaantammi, more people live near their work places as the largest number of commutes are made form areas near Kalasatama. People commute to Kuninkaantammi especially from areas near metro and train lines in Helsinki, Espoo and Vantaa. There aren’t many work places in Kuninkaantammi and therefore the number of overall commutes is very low, only 6 people at most. The Kalasatama residents often commute to areas in southern Helsinki. Some commutes are also done to nearby centers around metro and train lines. The Kuninkaantammi residents commute to centers easily accessible by train, for example, the Helsinki city center and southern Helsinki centers Pasila and Kalasatama. They also work in many Vantaa centers such as Myyrmäki, Aviapolis and the Helsinki-Vantaa airport.
