Urban Green Space Analysis

Urban green space analysis measures how much vegetation and parkland a city provides and how fairly residents can reach it, combining remote-sensing greenness, per-capita provision, and accessibility into evidence for planning and public health. Satellite vegetation indices such as NDVI map greenness pixel by pixel; per-capita ratios benchmark provision against standards; and gravity or threshold accessibility measures show who lives within reach of a park. As Wolch, Byrne and Newell argued, the analysis is inseparable from environmental justice — green space is unevenly distributed, and its provision must be designed to be 'just green enough' without driving displacement.
