City-scale greenspace exposure and inequality

1. Global_1028_cities_urban_boundary.shp This data represents the continuous built-up areas for the 1028 cities selected in this study. <br> <br> 2. Global_1028_cities_GE_Gini.shp This data represents the greenspace exposre and inequality assessment for global 1028 cities using the fine-resolution population and greenspace mappings. Key attributes in the shapefile data: (1) GExpo100m: Greenspace exposure assessment using 100-m grid without considering nearby buffer zones; (2) GExpo500m: Greenspace exposure assessment using a 500-m buffer disance; (3) GExpo1km: Greenspace exposure assessment using a 1000-m buffer disance; (4) GExpo1500m: Greenspace exposure assessment using a 1500-m buffer disance; (5) GExpo500mG: Gini index of greenspace exposure assessment using 500-m buffer distance; (6) SouthNorth: Categories of Global South or Global North; (7) Continent: Categories of continents; (8) lat/long: Latitude/longitude of the city centriod; (9) urbanArea: urban areas in Km2. <br> 3. Global_1028_cities_GE_Gini_four_seasons.shp This data represents the greenspace exposure and inequality assessment for global 1028 cities over four seasons (i.e., Spring, Summer, Fall, and Winter). Key attributes in the shapefile data: (1) GE_Spring: Greenspace exposure assessment in Spring using a 500-m buffer disance; (2) GE_Summer: Greenspace exposure assessment in Summer using a 500-m buffer disance; (3) GE_Fall: Greenspace exposure assessment in Fall using a 500-m buffer disance; (4) GE_Winter: Greenspace exposure assessment in Winter using a 500-m buffer disance; (5) Gini_Sprin: Greenspace exposure inequality assessment in Spring using a 500-m buffer disance; (6) Gini_Summe: Greenspace exposure inequality assessment in Summer using a 500-m buffer disance; (7) Gini_Fall: Greenspace exposure inequality assessment in Fall using a 500-m buffer disance; (8) Gini_Winte: Greenspace exposure inequality assessment in Winter using a 500-m buffer disance; (9) Gini_Dif_W: Greenspace exposure inequality difference between Summer and Winter using a 500-m buffer disance.
