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.

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.

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.
