Taking one step further – Advancing the measurement of green and blue area accessibility using spatial network analysis

Accessibility to green and blue areas (GBA) is one of the crucial factors in complex human-environmental systems, particularly in cities. Their quantification and mapping helps planners to reduce uncertainties in providing equal access to GBA or detect mismatches between supply and demand. Although...
