Data underlying PhD thesis: Green health. Examining the role of green space characteristics and their proximity in green space health pathways

The research objective was to examine if the significant findings between green space, air pollution and health stem from unique green space characteristics or similar mechanisms. This dataset is a correlation matrix of 135 green space indicators gathered in GIS, covering 9 different green space characteristics (mean surrounding greenness (NDVI 0-1), sum surrounding greenness (NDVI 0-1), mean accessible greenness (NDVI 0-1), surrounding green space (m2), surrounding green corridors (m2), surrounding total green space (m2), accessible green space (m2), accessible green corridors (m2), accessible total green space (m2), in 15 distances from 100 to 1,500 m every 100 m.
