“…Widely used indicators for green spaces usually refer to green space coverage (Fuller and Gaston, 2009;Zhao et al, 2013) or green space per inhabitant (ISO 37120;WHO, 2010). Others include also the proximity to green areas (Herzele and Wiedemann, 2003;Hillsdon et al, 2006;Kabisch et al, 2016;Morar et al, 2014;Natural England, 2010;Ståhle, 2010) or more complex indices referring to the balance between green and built up areas (De la Barrera et al, 2016). Furthermore, there are shape-oriented indices, which can also measure the distribution of green spaces (Margaritis and Kang, 2016;McGarical and Marks, 1994;Verani et al, 2015).…”
