| सारांश≠ | 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. | Accessibility analysis measures how easily opportunities — jobs, shops, clinics, parks — can be reached from a given location, combining the attractiveness (size) of destinations with the cost of travelling to them. The gravity-based formulation introduced by Walter Hansen in 1959 sums the opportunities at all destinations, each discounted by a distance-decay function of travel cost, producing a single accessibility score per origin that has become a foundational concept in transport geography and urban planning. |
